I am in a fractionalized T1 smart building. My isp gave me 5 ip addresses 63.209.32.130-135 w/ subnet mask of 255.255.255.192. I am running win2k server on .130 w/ a primary dns server, it recieves the T1 on .130 and it proxies requests through another card w/ RAT (10.0.0.1). The .130 nic has my isp’s primary and secondary dns for dns, and my .1 card has my primary and isp. on the same network, i have .131 as a secondary, it recieves the T1 also from the router on .131 and also is connected to network through 10.0.0.2. My clients are set to first look to my primary for a dns server then to my isp’s primary. i have registered my primary and secondary w/ networksolutions. my problem is this – my clients are unable to use my primary and default to my isp’s dns. when i perform a nslookup from my primary or a client, i am told that “can’t find server name for address 63.209.32.130: No response from server” when i then nslookup my domain, i get a non-authoritative reply w/ my primary. I believe the answer lies in creating a subnetted reverse lookup zone, as outlined in http://support.microsoft.com/support/kb/articles/q174/4/19.asp, so that i may be authoritative for my range, 130-135. however, w/ a subnet of .192 im not sure how that translates to .130-.135. also, the article says a subnetted infrastucture does not dictate such a reverse zone, its an administrative choice (although it doesnt appear to working otherwise) the article outlines steps my isp (parent) would have to taketo their reverse zone as well as steps i would have to take a far as i can tell. can someone please tell me what i have to do to get my dns working unde this setup?
