My ISP DNS lost its connection with the forum last weekend. I had to go into my router and change the DNS from automatic with ISP to manual and add in some IP address that I had from long ago. Does anybody know of good DNS address to use?

Do a search for opendns. I use 4.0.0.1 when others are failing.

4.2.2.2 is verizon ... I use them

Although this post is a little old, I would like to second OpenDNS. That's what I use, and I have not looked back.
