They are equivalent, but the former doesn't force you to invent your own naming scheme or use CNAMES (if using A records in in-addr.arpa domains is distasteful, then imho using CNAMES is even more distasteful, not to mention RR's containing the "/" character). --Adam
Why bother with CNAMES or A records? Is there anything wrong with simply using NS records for each adress? i.e.: $ORIGIN 109.246.64.in-addr.arpa. 1 NS ns1.customerA.com. 1 NS ns2.customerA.com. 2 NS ns1.customerA.com. 2 NS ns2.customerA.com. ... 16 NS ns1.customerB.com. 16 NS ns2.customerB.com. 17 NS ns1.customerB.com. 17 NS ns2.customerB.com. If the customer has a dozen name servers they want you to allocate reverse DNS for, it could become unwieldy, but technically, is there anything wrong with this setup? -Adam
