Ok. I have finally managed to finish my DNS service but there is a problem. DSL's upload time is not enough and T1 is too expensive for me so i have to go with a cable connection, but they cannot give me a static ip. So i was thinking if i could run my DNS service "hidden" and my secondary Dns is going to be from secondary.com. Now if i make my primary nameserver hidden, would so the secondary.com's service would look for my ip right? And would it work? If it does, how well do you think it would? If my ip changes i can just change it at secondary.com and it would take affect without changing my ip from the ICANN which would not take two days. What do you guys think?
