Reverse DNS: Difference between revisions

→Reverse for /24 or larger

Your WAN address and any other single addresses are still individually delegated as their own zone as above.
==IPv6 Reverse
IPv6 is delegated at /48 or lower by NS
==Reverse Delegation for /24 or larger==
If you have a block of 256 addresses or more, then reverse DNS delegation is done at the /24 level and setting CNAME or NS has the same effect. This means you are responsible for an entire reverse zone without the need for special CNAME entries, etc. Most people do not have such a large block of addresses.
