69.147.114.210 = yahoo?
64.233.160.104 = GOOGLE?

I had a customer lose internet service with Comcast. When I used to have Comcast, they used to lose the DNS server on a more frequent basis than I think ought to happen with an ISP.

I used to test with one of the above IP addresses, but they won't WORK from my location. Would a firewall block an IP address? Why would it "care"?

Is there an easy way to get a site's IP, just for future reference?ping google.com

from a command promptYeah, I knew that.

I'll check to see if they've changed.

Thanks for the suggestion.

I also ought have remembered that IP addresses are not WRITTEN in stone -- not by far! The reason the above addresses weren't working is because they're no longer valid! (To think that Yahoo and Google didn't "clear" this with me!) Were you asking something different? Maybe I didn't understand.No, we're fine!

As I EDITED above, the addresses had simply changed!

Going to the sites via IP address works just fine when the addresses are correct!

Thanks, again, for the suggestion. I wish they were all that easy! The OpenDNS service might help customers such as these. They're not obliged to use their own ISP's DNS servers. OpenDNS provides other benefits too, such as a MEASURE of rouge site protection.
