If you see the whole picture you willunderstand :
ISP makes a CNAME for (45) in 66.123.22.45 in their 22.123.66.in-addr.arpa :
45 IN CNAME 45.customer.net.
And the cuetomer in his zonefile for "customer.net" does
customer.net. IN SOA ...
IN NS
IN NS
www IN A 66.123.22.45
45 IN PTR www.customer.net.
Works with bind, all versions, works with ( if anyone should care about it)
w2k, does not work with NT ( but again, who cares)
