I have to do this on a couple of blocks here, the piece of named.conf that is of interest is just: zone "128-26.254.181.205.IN-ADDR.ARPA" { type master; file "zones/205.181.254.128-26"; } and the zone file looks like (changed domain name for no good reason) @ IN SOA domain.dom. email.domain.dom. ( 124 86400 900 120000 3600 ) IN NS ns1.domain.dom. IN NS ns2.domain.dom. 129 IN PTR name.domain.dom. ... 190 IN PTR lastname.domain.dom. On the server with 205.181.254.0/24, the NS record looks like 128-26 IN NS ns1.domain.dom. 128-26 IN NS ns2.domain.dom. then each address has a 129 IN CNAME 129.128-26.254.1181.205.IN-ADDR.ARPA. line with it. I've found AT&T at least like to use / instead of - in the rev name, so it end up looking like 128/26.254.181.205.IN-ADDR.ARPA instead. -- Chip Marshall http://www.chocobo.cx/chip/ Finger for PGP GCM/CS d+(-) s+:++ a18>?
