Thats the difference between someone that can use different material to explain something to you in 5 minutes vs someone that can't do either and it takes him 3 hrs before you understand .. Some people were NOT meant to be teachers even though they are. NOT all people understand the same thing, some have to be taught differently to understand, thats the marvel of the human brain. I am a field tech for a major ISP and my job is to explain to customers what their internet speeds are and how much they need because not all, 95% of my customers are clueless to what internet speeds are let alone know how much they need or they THINK they need because Customer Service told them that because they have 3 smartphones in their home that they need 100Mbps ... LMAO ... While he went thru this video pretty fast and most of it was correct, he could have done this in 3 minutes ... Bottom line is that if your device is ONLY IPV4, that means you cannot access a web site "server" that is on IPV6 only ... This is what happens when smartphones or laptops or tablets or desktops that are OLD like over 10 yrs will stop being able to access the web because most companies have changed over to IPV6 due to the amount of devices that are accessing the web. Like he said IPV4 only supported 4.3 billion devices which was hit around ~2012, thats when IPV6 started up to allow more devices to connect to the internet.

U know why cuz he doesn't have a Sponsor 😂

@@TusharSharma-bp3rt the ones that take a 10 min video to explain something that really takes 1 min are those that are getting paid by youtube and the MINIMUM the video has to be is 10:05 with 2 commercials that cant be skipped at all before you get paid. This is why they always say, SUBSCRIBE AND LIKE AND HIT THE NOTIFICATION ... so they can get paid from you watching their video..

@Cy McHargue cat got your tongue ??

Yeah the only reason I did this topic was because I've gotten so many requests. It's not something that I thought was the best topic ever for this format... But we did our best with it.

Techquickie Well, i have to say you explained it really well for me! thanks a lot, I only get excited for a few channels when they upload and your channels are part of the select few. rock on linus :D

A Triangle? Or is it the illuminati?

IPv5 was taken by companies like IBM, NeXT, Apple, and Sun in an ST2 around the 1990s for their networking. Rather than taking over this experimental service companies decided to upgrade and improve the IPv4 connection into IPv6 during nearly the same time frame, so it never caught on. Similar story to company skipping a line of products IE going 1,2,3, then 5. The 4 existed at least in testing but never made it to the public for some reason. Hope that made sense. I did a little search in google for IPv5 and that is what I read from multiple websites.

Thanks. But that seems strange to just skip numbers whenever something isn't 'finished' enough.

+sniperlif3 Close, those companies were trying to improve on IPv4 but didnt resolve the issue in time before IANA (governing body of internet based protocols) routers were required to become stateful and retain data. So IPv6 came out. www.iana.org/assignments/version-numbers/version-numbers.xhtml (bit of a boring read if you cant decifer it) www.alertlogic.com/blog/where-is-ipv1,-2,-3,and-5/ IPv0-3 were experimental where they were trying to move from Darpanet to true internet but realized they were failing at trying to make TCP do two things at once while messing up layering and thus IPv4 was eventually ratified as the standard. The only downfall to IPv4 is they could never have predicted that the need for more then approx 6 billion devices would need a public facing IP (we are currently well over 10 billion hitting the net, but sub netting helps a lot there). Also keep in mind that at the time they considered 50MB of HDD space to be an extreme amount that no normal person would ever need to make use of. Those previously mentioned companies tried to solve this with IPv5 (to make it their own in a sense and charge for it) but ultimately timed out and the rest of the community developed IPv6. Which in theory, can provide everyone on earth alive now with at least 100 statically assigned addresses and not run out using IPv6. Although, I suspect by 2050 we will be addressing IPv6 limitations. Who knows time will tell there.

Yea, since IPv4 addresses are 32-bit long, the numbers are ranging from 0 to 2^(32/4)-1.

for anyone who was too lazy to do the math, that was 255.255.255.255. Heaven forbid if Linus showed a 8 octet IPv6 address in hex with abbreviations where an octet had leading zeros. :-)

GF is studying TCP/IP and she picked it up !

Anon ymous i knew someone would comment this. Linus did this because if he showed a real ip address, that’s someone’s address. that’s not right. that’s why he’s using fake unrealistic numbers. duh

Speaks like everybody know their IP addresses

Its no big deal really tho

@@PoleTooke zoo wee mama!

He did that for the same reason Movies and TV shows always use "555" as a phone prefix. They don't want millions of people trying to dial a valid phone number and jamming it. Linus did not want his viewers pinging a particular valid IP address. Movies and TV shows do this for IP addresses as well. There is a scene in "Iron Man 3" with 614 as part of an IP address.

Agent57000DM he could just use private range ip

because he would totally put a real ip

@@Agent57000DM Yes, I'm replying 6 years late, but they actually should've used one of the IPV4 addresses that are reserved for "documentation and examples". 192.0.2.0-192.0.2.255 198.51.100.0-198.51.100.255 203.0.113.0-203.0.113.255 233.252.0.0-233.252.0.255 Are IP adresses reserved by ICANN to serve as "example only".

+Pritish Patil This is likely done so that legitimate IP addresses are not accidentally used.

There's no harm in displaying real IP addresses...

Pritish Patil​ There's no harm in not, either.

showing wrong ipv4 addresses, makes it worse...for people who are new to ip addresses.

+Pritish Patil In this case, I hardly think that using arbitrary numbers makes what they're referring to ambiguous, and the space of correct addresses is not really relevant to the subject of the video at all. Think of it as a "lorem ipsum", a piece of text that serves no purpose other than to illustrate what some text might look like in a certain format.

Why is it outdated? Because the standard got set 16 years ago doesn't make it outdated. The IP protocol was made to get data from place A to place B. What exactly has changed the last 16 years that would make IPv6 bad? And the switch will happen. There is no way around it. We've come to the point where big companies are starting to hoard IPv4 addresses because ICANN has handed out the last blocks to regional providers. Especially in Asia the demand is so large that a full switch to IPv6 is imperative to keep everything running, but even over here where I live I am now running dual stack. The largest ISP in the country has rolled out dual stack internet connections to everyone with a compatible router. When a site supports IPv6, that's how I connect to it.

Niosus 2 major things changed: we have a lot more mobile internet connections and a much higher demand for security and privacy. Mobile bandwidth can become an issue with the much bigger header size (overhead) of ipv6 and addres autoconfiguration brings great privacy leaks such as publicly announcing your MAC address. Apart from that, we would still need NATs as a security feature and renumbering wouldn't really help against core routing table fragmentation and firewall reconfiguration. Over the time we also became quite dependent of ipv4, because not only the network, but also the applications have to support IPv6, which most don't. So we can't just change the network technology and just keep working. Also, switching to IPv6 in just a part of the Network would seperate it from the rest, as the two are not compatible. So if you have a IPv6 connection (as some ISPs already do) and want to access a IPv4 service (like basically any website), you will need features like tunneling (ipv4 over ipv6) for it to work, so there will still be IPv4 addresses and maybe even inter-technology NATs. And it's the same problem in the other direction, if you want to access IPv6 services, but you're only connected by IPv4. Dual stack is the only real option for a switch in technology over the long term, but it is so insanely expensive that it would/will take a really long time to support it. and servers have to either use dual stack as well, or they switch at a certain point, if enough users support IPv6. Apart from the software problem. The change seems to be at its start, but don't expect IPv6 to be really used in the next 3-5 years. Right now, there is no added value for customers if they switch (rather the contrary if they made a full switch, no dual stack) and DHCP and NAT work good enough. The few advantages of IPv6 are just not good enough.

it's not outdated.. is not being used because it would be expensive to set it as an standard..

unnAMDable there is no doubt thet it's not used because it would be to expensive. but still the time that standard has been there without being used could have been used to define a better new standard that really solves more than one or two problems and brings enough benefit to invest the cost.

Tobias Berger In most of your reply you talked about how hard it is to switch, not why IPv6 is not a good solution. The header size does increase overhead, but the IPv6 header is much more compact in the sense that much more of the header is used for the addresses. 8/20 bytes in IPv4 are used for addressing compared to 32/40 in IPv6. There really isn't much you can do to get over this problem, no matter what standard you'd like to use. Either way, mobile networks today are faster than land networks in 1998. This is not a critical issue. As for security/privacy: Modern devices will not broadcast their MAC address. Privacy extensions that randomize the host identifiers have been in OSes since XP SP1, making IP based tracking about as effective as it is now. Using a NAT as firewall is a terrible idea. It was never meant to be used as firewall and should not be seen as one. It only just so happened that it did share some properties with a firewall. There is no reason why an IPv6 router cannot have a default firewall set up to act much like a NAT table. Also nothing is really stopping you from implementing NAT. The IP protocol doesn't know about NAT and doesn't care. If you want NAT, nothing is stopping you. Sure the transition won't have its problems, but compared to the amount of hacks we use to keep IPv4 functioning it is a huge improvement. Of course hindsight is 20/20, but it has taken over a decade to get marginal adoption of this new standard. We cannot wait another decade to get a new standard up and running.

Hahaha. Maybe they are sinister. File a collective Complaint or something? Probably not a great idea but it's definitely time to upgrade to Atleast somewhat modern ways.

Same here. Verizon FiOS is IPv4-only in most locations. Sure, you can do a 6in4 with Hurricane Electric to get IPv6, but some parts of the Internet block their IP space, Netflix included. I appreciate the ISPs who Dual Stack IPv4 and IPv6.

Europe just ran out of ipv4 addresses

ah the good old days before corona,

we need IPv6 because we're running out of IPv4 addresses. IPv6 will make the Internet faster and simpler, but will require equipment to be updated that the ISPs are reluctant to spend money on.

Techquickie I just wish the video had subtitles in Spanish so I could understand better haha ....I follow you from South America

Techquickie Isn't IPv6 also encrypted aswell?

GhostMotleyXT No. As long as your packets meet the specifications of the protocol, you can send any data you wish. The sent data can of course be encrypted, but they don't have to.

***** You really think every subscriber has a backround in computers or networking? I only knew the stuff in this video because im going to college for networking and i doubt every subscriber of Techquickie has gone to school for this stuff.

underpantcockroach That was quite possibly the best comment I could hope for.

DDoS :3

stevenmael that would require them to have a botnet and if they are acting the way op said they are probably just 12 y/o script kiddies who get confused between dos (denial of service) and ddos (directed denial of service)

TheEpicMusic161 XD i know im just messin around

stevenmael ok XD

i guess he was trying to elaborate on the point that there are 'not enough ip addresses'

No

Well... Technically not. Since the network card could just have it's own unique IPv6 address like it already does with mac address.

Not really true. IP address is assigned by router. If you built a mac address based routing system, and then you moved your computer, it is completely possible that your computer could no longer be found by the internet.

Oscar Smith Well that is why i said technically. Since the question was if *everything* was IPv6. In which case the router would no longer assign anything to the machine. But rather the machine's network card tell the router it's unique IPv6 address once a connection is established. However if this were ever to happen it wouldn't be until probably a few decades. As taking use of such a system would be completely incompatible with our current system. Meaning migrating to such a system globally would be extremely difficult.

Haakon Hawk isn't the transition to ipv6 already happening

Mac is layer two and only used in a LAN, so ass long as the devices on the LAN are compatible there is no problem using such an ethernet protocol. But then again, i don't think that will ever happen, since MAC is layer 2 and IP is layer 3.

melbin mate

+misterhamez LOL - kin oath, mate.

all of it comes down to the fact that AC power that comes from a mains plug isn't smooth (in other words the power goes up and down slightly and a computer chip needs an exactly flat line to be efficient and to be stable), a capacitor holds the charge for short time and then releases it in a predictable way which means it is smoother, not completely smoothly though so they introduce extra "Phases" a phase is basically like splitting the power out through a bunch of different lines, smoothing each line separately using the capacitors i just mentioned and then putting them back together again resulting in a much smoother power delivery. Chokes normally go on the end of each phase, what they basically do is slow down the flow of electricity, this means that for example if there is a power surge, it is slowed down so the surge doesn't reach the chip, preventing damage and again working as a final method of making the power delivery smoother. Source: the past 3 years i have spent being an electrical/electronics engineering student :)

ac from the wall is for example in usa 60hz in other contries 50hz that means the current constantly changing between being positice and negative depending on hertz ex. 50times a second for the same reason some people says that their bulbs flickering not all ppl can see that.. there is a bunch of videos in YT witch show bulbs in slow motion p.s gramar nazis dont judge me english isnt my primary language

oh if you currious why ac instead dc? with ac you can easily transform voltage as well as change current many power lines is ultra high voltage because that way the current is reduced and results less power loss lower amps less heat produced less loss transformation with 100% eff is 200v0.5A transformed to 100v now have 1amp so yea and all those chokes etc. is used to make current super stable witch is critial for parts like cpu depending on ex. cpu load power draw changes and voltage can drop and raise depending on those factors witch as i said is bad for those parts so those fancy thinks stabilise voltage with capacitors help why psu cant do that? psu use switch technology witch is based on capacitors depending on load switch turn on and off to keep voltage in capacitor thats why some psus buzz when there is no load and switching methood is good coz its more compact but it still has tiny voltage fluctuation many phone chargers based on this

and while i was typing reply in my phone i accidently sit in wrong bus and it cost me a bunch of money and time dang it :(

Isaac Karjala it's clearly not just people that don't know anything that are watching the video.

57worldwide Yea.... Though if you are looking to attack a random target it is not that hard to come up with an IP, just ping a random domain and it'll give you there IP. If you are worried that someone will actually try attacking the host just for giggles; Hak5, CCC, Nmap and others host honey pots for hackers to hone there skills on; if you're worried about a Slashdot style DDoS, just list the IP of a distributed service like OpenDNS.....

I have never heard it said like that.

Mac and IP are different things and IP6 isn't going to stop you from spoofing a Mac addy, if anything IP6 just gives you another addy to spoof.

A modem converts the analog signal from your phone line into a digital signal that a computer can understand. A router is a device that gives a signal to devices. A wireless router is the same a router but as the name states it's wireless. It's possible to run an ethernet cable right to the wall but it can give sercurity problems. A router can sercure your connection.
