Routers, Static IPs, and DNS
Posted: 2004-09-17 09:34am
What's the easiest way to set up a static IP address for a computer on a network with a NAT router (Linksys)?
Now, I've been using static IPs on the router for a long time for port forwarding. However, I had to find my ISP's DNS servers and tell them to each computer I gave a static IP. Not too difficult, since they're given on the router's Status page.
Last time I was playing around with it, though, I tried putting the router's IP address in as the DNS server and surprisingly enough, it worked! I did this on a Linux and Windows 98 system with no trouble. Power went out a few times, but that's unrelated.
Now here's the odd part. The other day, the power went out in a storm. When the power came back on, everything was fine except both of the static IP systems couldn't resolve any addresses. I put the ISP's DNS servers into the network properties and everything was fine again.
But my question is: what would cause a router to apparently forward DNS requests to the proper servers for a period of time, then suddenly stop? I can't figure out if I had it doing something it shouldn't, or if it's now not doing something it should do....
