What is a glue record?
Suppose that I want to have custom nameservers that authoritatively host mydomain.com
: ns1.mydomain.com
and ns2.mydomain.com
. They would need to be resolvable somehow for the rest of the internet to be able to use them, but how is that possible when the nameserver records are rooted under the domain that they're authoritative for?
