Hosting DNS in house

[jonks]

At present we host numerous websites in house. We have a internet connection to our ISP and we use their DNS servers. We are about to change ISP and would like tohost our own DNS servers for our Websites. This would make changing ISP's in the future a lot easier. I wounder if anyone know where i can get some information on how to set up DNS and how i would divert our websites over to using our DNS. I know DNS works on a tier system and i getting a little confused as to what i will need to do to make the redirection propagate through the Internet.

DNS is new to me and i am finding it dificult to get my head round it at the moment.

Thanks in advance.

While it initially sounds like a good idea to be ISP-free for ease of DNS adjustments, I'm not sure that it would turn out that way. When you change ISP, you have to change your public IP addresses (at least, I always have had to). Changing the public addresses of your DNS services with domain registries sounds far more difficult and painful to me than changing DNS records for the same domain names.
