Hello,
I currently have a server with a semi-static ip on an ISP which blocks port 80, we have been using a free service which maps our ip to a domain name and then using another that maps that and an alternate port to yet another domain name so we can get around the ISP block. This is rather cumbersome and annoying, thus I was hoping that we could buy our own domain name and do our own dns listen but I have found very little info on setting up your own dns server or how to list your info into the larger system. Does anyone have any place to look for more info on this? Or any suggestions on how to solve the problem another way?
Thanks!

Setting up a dns server HOWTO

If your ISP has a good reason for blocking port 80, would they also block https on 443 or dns on 53?

How about using the <meta http-equiv="refresh" content="1; url=my.domain:81"> tag in a remote webpage that redirects to your ip/name on port 81, if you can borrow some space that your domain can point to

most servers DNS use port 53 if port 53 is open oh your isp u can run a dns server as for apache like web servers use port 8080 insted it will still run a webserver on port 8080 :P
