I have a...friend, let's say...who operates a DNS server at a small ISP. In a few of the zone files, there are A records that resolve to IP addresses outside of the Class C that my..friend...controls. My friend has been told that this is "against the rules" and that it is "causing problems".
(a) "class C" is a historical term, and has no meaning on today's Internet. (b) The data that any zone administrator installs in a zone is nobody else's business (at least, from a technical perspective; publishing a screener of the latest harry potter movie in TXT records might have legal consequences, however). So:
Questions: - is resolving an A record outwith the delegated IP range "against the rules"?
No.
- if so, is there any documentation of the rules? - what potential problems could this cause to the network that contains the IP address to which the A records point?
In and of itself, none. Joe
