Hi, I've recently setup an external DNS server (eg: ns1.domain.com, 64.22.33.40) to resolve addresses for my web (www.domain.com, 64.22.33.41) and mail server (mail.domain.com, 64.22.33.42). The forward lookups are working correctly. When I ping to ns1.domain.com, www.domain.com, etc.. it points to the correct IP. The reverse lookups do not work however. I've setup the ptr (ie: 64.22.33.41 points to www, 64.22.33.42 points to mail, etc)... but when i do a nslookup (41.33.22.64.in-addr.arpa), the name of the server is totally differnt than what my servers are called. I don't know what the problem is... could it be that my ISP's DNS server is picking up the reverse lookups before my DNS server is being queried? Do I need to register my DNS server in a .com directory? Right now my .com registrar company has a DNS setting where I put in the IP and name of my DNS server (ns1.domain.com, 64.22.33.40), is this the right place to put it or is there more? Thanks for your help in advance D

Sounds like you are trying to put your Dns server on the internet which you can not do. I am surprised your ISP isn't screaming at you yet. If I ping domain.com I get a 216.x.x.x address response. You need a REGISTERED domain name. Then the public dns servers will have the correct entries and route requests for that domain name to your servers. Golly gee wilerkers everyone.

Hi Wanderer, Thanks for your reply. domain.com was just an example I'm using, my actual domain name registered is not domain.com. So what should I be doing if I want to have my own DNS server? Right now I have a web server, ftp server, exchange server and others (6 in total) that need to be publically accessable. The ISP has given me an IP block of 8. If you could provide me with additional information that would be greatly appricated. Thanks! D
