OpenDNS and private IP addressing
Several years ago my ISP’s DNS servers were down and I went looking for a replacement and came across OpenDNS. I found web sites responded faster and I was very happy with the service. Unfortunately I barely scratched the surface of what OpenDNS can do.
A friend was looking for a way to filter or block adult content on their home network: there is software available but I thought of OpenDNS and knew you could do it for free, as with all their functionality.
During my testing of the Windows Home Server beta I found the software couldn’t find my home server by name: I then found I couldn’t connect to any PC on my home network by name. It had to be an OpenDNS issue but I couldn’t figure out how to resolve it so I went back to my ISP’s DNS servers. I hated it: they were using their own not found page and response was slow.
Perusing the web I found a mention that OpenDNS had afor this and it must have been a got topic as it appears close to the top of their support articles. Basically you add an exception for your private IP range: most home networks are using 192.168.1.* or 192.168.2.*. Once I had these in place OpenDNS and I were united again.
