reverse dns

Hi, I got a dedicated server with 2 IPs. I asked my provider (valueweb) to setup reverse dns. One IP got setup, but the other didn't. I'm looking for some confirmation that the problem isn't on my end.

207.36.160.28 was setup properly, but the IP I really need setup, 207.36.180.93 (vw.zworg.com) doesn't work.

$ dnsq any 93.180.36.207.in-addr.arpa ns.valueweb.net
authority: 180.36.207.in-addr.arpa 86400 NS ns.valueweb.net
authority: 180.36.207.in-addr.arpa 86400 NS ns2.valueweb.net

which loops...

the one that works
$ dnsq any 28.160.36.207.in-addr.arpa ns.valueweb.net
answer: 28.160.36.207.in-addr.arpa 3600 PTR vw.nothsa.com
authority: 160.36.207.in-addr.arpa 3600 NS ns1.primarydns.com
authority: 160.36.207.in-addr.arpa 3600 NS ns2.primarydns.com

ns1/2.primarydns.com is where the PTR records are supposed to go I believe. So it looks to me like valueweb needs to change the ns records for 180.36.207.in-addr.arpa to ns1/2.primarydns.com (and maybe put in an soa record for 180.36.207.in-addr.arpa in the ns/2.valueweb.net to ns1.primarydns.com hostmaster.primarydns.com)?

If someone can tell me if I'm on the right track with this (and if it is or isn't my problem) that would be great!
thanks,
Tom

Because they are clueless.
