When to add glue records to your nameservers

Glue records solve a common chick-and-egg problem in DNS, but they come with a caveat.

Why don't NS records contain IP addresses?

Thanks to imMute and Habbie for reviewing an earlier draft of this video.

Gosh this was understandable. Noone can't even try to explain things that easily and consisitently.

Thank you for all your videos and effort : ) All of this stuff might seem convoluted but in your words its extremely accessible.

That's super interesting! I do wonder though, if you asked for a specific domain, and it has the necessary glue records, couldn't it respond were those if you asked it for that domain directly? It would make sense to glue those things on in the case that you know they are going to be requested anyway, to require one less DNS lookup - though now that I think about it, that could actually be the answer, with it still pointing to the DNS server with an NS record for consistency?

Either way, that's a very interesting implementation detail (well, implementation detail for those who don't have to deal with where the name servers for their stuff are), and a well made video about it :)
