So I'm running a website off my own server. I piggybacked off my dad's domain; I added subdomain, evamsharma.finosus.com, and pointed to our network IP, and set up port forwarding. But when I logged onto it this morning, our IP had changed. It has stayed stable before, but I guess my ISP uses DHCP. Anyway, I need to know how to point my domain at my router even when the IP is changing. I looked at No-IP, but I couldn't figure out how to use it with my existing subdomain without transferring the domain registration to No-IP, which I couldn't do because my dad needs that domain.]

What can I do about this?

You set up no-ip subdomain on your ip address, set up the dynamic DNS client and make sure it works then set up a cname record for evamsharma.finosus.com pointing at the no-ip subdomain.

No-IP seems only to have options for subdomains for a specific site that they own....if I wanted my domain to still show up in the address bar, how would I do that? –  evamvid Feb 15 at 3:41
Thats why you set up a cname record - a cname record basically says "if there's any requests for evamsharma.finosus.net, send it over to somedomain.no-ip.com" - as such you need to basically replace the A record for evamsharma.finosus.net pointing at a IP address with a Cname record pointing at FQDN. –  Journeyman Geek Feb 15 at 3:43
So what I'm doing is setting evamsharma.finosus.com to point to the No-IP IP. In turn, the No-IP IP points to my server, regardless of my network's changing public IP. Right? –  evamvid Feb 15 at 4:06
It worked! Thanks! –  evamvid Feb 15 at 5:34
It'll work until your ISP decides to block you. I highly recommend you read your ISP's Acceptable Use Policy. Caveat emptor. Consider a cheap VPS or cloud provider if you are serious about having a web site. –  milli Feb 15 at 9:04
