I have Charter and have the same problem, had to enter this today 209.157.64.200
It was different yesterday.
- Enter 208.67.222.222
- press return
- Enter 208.67.220.220
That is the actual IP (Internet protocol) address of the FR server.
208.67.222.222 and 208.67.220.220
Those are the IP addresses of the DNS (Domain Name Service) servers for OpenDNS, which apparently still has the database entry for FR (that "translates" www.freerepublic.com to 209.157.64.200).
