Why is OpenDNS blocking sites in Safari?

I upgraded Safari last night through Software Update.


This morning I tried to go to one of my regular sites and OpenDNS blocks me from it.


I don't use OpenDNS. I did a couple of years ago when I was having speed issues with Safari. It didn't help so I dropped it. Turned out that was a modem problem that couldn't handle DNS prefetching.


So why is it back? Why is it blocking me? And how do I stop it?

It's been fixed. Plus I went out and had dinner an a couple of beers.


Apparently my ISP assigned me a new IP address used by a former OpenDNS user that blocked my sites. An admin at OpenDNS released the IP to my account and no sites are blocked now.

Thanks. I'll set that up.

Which they most certainly will do again unless you pay extra to get a static IP address.


What you need to do is use a utility which checks your IP address periodically and reports changes to OpenDNs. I used one that they provided for awhile, but it failed a in it's job somewhere along the line, so I switched to DNS-O-Matic and it's been flawless.
