Nice video Troy! Although, I am having trouble configuring the IP to static. It would have been beneficial if you added how you configured the IP addresses in the video or a separate video to follow along 100%.
at 25:00 you needed to manually create a record for PC01. A new A file for PC01. What if PC01 was getting its IP address - leased from DHCP..... so in a week it would have a different IP address.... how would DNS update itself?
Hi Jason, great question. During a DHCP lease period, the PC has a special set of intervals where the PC tries to renew and extend the lease. We call these the T1 and T2 intervals and, generally speaking, as long as the original DHCP server remains reachable and there are no administrative restrictions to the contrary, the PC will extend the lease with the same address indefinitely. However, if something were to change with the lease address, if we've configured DNS to update dynamically, we'd see a new A-record and a new PTR record created automatically. Behind the scenes, DNS uses something called DNS scavenging to delete and get rid of expired records. The default for this cleanup is every 14 days, but you can configure it at different intervals if you wanted. In this video I was configuring standalone DNS to try to show general DNS concepts and I didn't configure dynamic DNS (hence the need for the manual record management). DNS is much tidier and more intuitive when it's working in conjunction with Active Directory, and I deploy dynamic DNS here in case you're curious and have time to take a peek: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-joIubWzQ6P8.htmlsi=-AqoQ8lyRje0nnz8 Thanks Jason!
