Re: [PLUG] DNS Question

Ok, I have 2 servers, with 2 dynamically assigned ip's. Both use the same domain of v-system.net. One server runs OD, DNS, mail, web, ftp, ...etc. Both are behind nat'ed firewalls but not connected internally to one another. Both are running the noip dynamic ip client so their wan ip's are tracked. My primary dns zone is on the OD server. These are comcast lines as well.

If I do

[macserver:~] root# nslookup v-system.net
Server:         192.168.1.102
Address:        192.168.1.102#53

Name:   v-system.net
Address: 69.139.74.31

[macserver:~] root# nslookup 69.139.74.31
Server:         192.168.1.102
Address:        192.168.1.102#53

31.74.139.69.in-addr.arpa       name = macserver.v-system.net.

I'm amazed that the reverse lookup locally record doesn't come back as comasct

[macserver:~] root# nslookup v-system.net.local
Server:         192.168.1.102
Address:        192.168.1.102#53

Name:   v-system.net.local
Address: 192.168.1.102

[macserver:~] root# nslookup 192.168.1.102
Server:         192.168.1.102
Address:        192.168.1.102#53

102.1.168.192.in-addr.arpa      name = macserver.v-system.net.local.

[macserver:~] root#

The other server is called the redqueen.v-system.net which is on a different dynamic ip
[macserver:~] root# nslookup redqueen.v-system.net
Server:         192.168.1.102
Address:        192.168.1.102#53

** server can't find redqueen.v-system.net: NXDOMAIN

[macserver:~] root#

My question is why doesn't it resolve to the proper wanip address. If I go to the web and use a web nslookup tool I get the correct address.

Sincerely & Thanks In Advance
