Welp, TIL. I tried a reverse lookup for a site I own and indeed got some long string of `a134124randomstuff.awsglobalaccelerator.com`. I suppose I naively assumed that if I put an IP address in the A record, that would be how it resolves. Clearly not! I guess whatever's under the hood of the NS records probably adds a few translation layers. Will have to read further, thanks!
- mercora 5y agoit is just a different record entirely. there is a special zone for reverse lookup on ip addresses for ip4 and ip6 respectively. the address gets transformed into DNS labels to make the lookup. i.e to do a lookup for the ip address "192.0.2.1" the actual name for which the lookup is done is "1.2.0.192.in-addr.arpa." and the delegation for these zones can be and typically is entirely different from the forward zone. if you only have access to the forward zone you wont affect the reverse zone at all...
