I have been having issues with DNS resolution being extremely slow with Charter Communications Internet on my Macbook. I tried disabling IP v6 in Firefox and that seemed to work for a little while, but eventually my DNS lookups slowed down again. Frustrated, I began looking for ways to not use Charter's DNS servers.
I found out about OpenDNS after googling a little bit. I opened up a free account and switched my router over to their DNS servers. Low and behold, my Internet speed is blazing again on my Macbook. So, if you're having issues with slow DNS lookups on OSX and Charter is your ISP, give OpenDNS a try.

For the last 3 years, I have had OpenDNS manually set in my routers DNS boxes. When I do that now, I get 0.0.0.0 as an IP address.
If I let DHCP from the modem give me Charter DNS servers, I get my regular 97.x.x.x IP address and I can surf.
I called Charter tech support, and they told me it was an OpenDNS technical problem.
The plot thickens as I had Tomato firmware on my router, and now, with Tomato firmware loaded on the router, the only way I can get an IP at all is to clone the MAC of the PC. If I use the routers MAC or a random MAC, I cannot get an IP even if I use DHCP for DNS. If I use Linksys firmware, I can get an IP because Linksys pulls a Charter DNS in the #3 slot. If I put OpenDNS in all the DNS slots with Linksys firmware, I get 0.0.0.0 as an IP address. As soon as I leave #3 open for it to pull DHCP, I get my 97.x.x.x IP back.
I see nothing in Charter's TOS that prevents me from selecting my own DNS, but, they certainly are forcing it on me. I have verified this with TWO different Linksys routers.
Thanks
