| [HSI] How to not make friends with DNS
Okay, I finally got tired of Charter's mucking up the DNS. As soon as they did that update a few months ago, it all got worse. Sites wouldn't resolve, the search page would come up on sites that I knew existed, etc... etc...
I finally gave up and put in static DNS addresses tonight, mostly because at about 6:30 PM (PST) the router started receiving blank fields for DNS address (Oddest thing I've ever seen. I did a renew several times and everything showed up except for DNS.)
So, static is working for me. But I figured I should let someone here know that DNS just took a step backwards.
This is the Pasadena, CA area. |

| I am using OpenDNS which works awesome.

You might try manually setting your DNS to the OpenDNS servers and see if that works for you. |

Any answer to a dns question or problem with charters dns servers, is to not use charters dns servers. Solves the problem 100% of the time. |

Acually on charter dynamic account you cannnot fully use open dns. Hence as far as i know ther is no way to hard code open dns in those modems.
If i am wrong on this please correct me and tell me the procedure to get it done. |

| Um. You don't hardcode it into the modem, you hardcode it into either your computer TCP/IP properties if you do not have a router, or you hardcode it into your router if you have one. Bingo problem solved. I quit messing with Charter's DNS 3 years ago. It is ashamed that a service provider can't provide a reliable/good DNS server of their own though.  |

| Well if you botherd to notice unless opendns or what ever dns you want to use is hard coded int the modem its 50/50 what dns you will be using at anyone time.
I know this from watching my iftop on my smoothwall box.
there is a way to make a patch to force smoothwall to insist on what ever dns you want.

Your basic cable modem is just a bridge, and there is no call to the modem for DNS. That is done in the router, or on the computer.
If you have a combo modem (router+modem), I would expect it to be configurable.

Not sure what you are looking at, but the behavior doesn't sound like a normal cable modem to router setup.

1 edit | Here you go i made a screen shot for you.
This is one of charter dns servers.
vip01ftwotx.ftwo.tx.charter.com
the 10.89 ips are peoples modem ip address.
as you can see it is hit and mis i have a open dns entry as well as the charter dns so there far its 50/50.
open dns is hard coded in my smoothwall config in every router and or computer behind it.
And on a bridged CBN modem Yes you can have dns hard codded in the modem itself which would resolve the issue.
Im also being nailed from this ip
68.114.37.166 (68-114-37-166.static.stls.mo.charter.com)
10:47:58 eth0 » - UDP 68.114.37.166 67(BOOTPS) xx.xx.xx.xx 68(BOOTPC)

I assume you have DHCP addressing from Charter and not static? Whatever you have connected to the modem whether it be the smoothwall or your router receives the Charter DNS server addresses by DHCP. You'll have to look deeper in your configs to see if there is an option to override that and specify a DNS server on that interface. Most likely the reason you are seeing a connection being made in the smoothwall log is the device receiving an address from the modem is making a DNS request for a NTP server. Everything else in your network receiving the hardcoded opendns by way of DHCP or static assignment is using opendns and never that Charter DNS server. It has nothing to do with coding an address in the modem as you can't. |

Whenever I try to use Open DNS by putting it into my WinXP's TCP/IP properties, it won't let me access Google. So far that is the only site I cannot access. When I let charter pick the DNS, Google opens fine. What gives? |

When I first used charter like say 7 years ago. Since then I have NEVER EVER EVER used their DNS. It just stinks. I go to friends's houses and use their connection and I am appalled at how charters DNS servers suck.
I secretly change their DNS servers to 3'd party server and they never have a complaint.
Then call me up and tell me "Kris. wow, our internet is working better since you go on the computer! Thanks"

Yes, I've tried it both ways. Very strange. Soon as I put the Open DNS numbers in it stops working for Google. Soon as I take them out, everything is fine. That's the only site that doesn't work for me and wouldn't be a big deal, but I use and like Google a lot. |

OpenDNS runs a google proxy 'as a service for you' This probably explains why google breaks when you use OpenDNS.

There is no requirement, than common convention, for a URL to include the 'www' in the FQDN. The site operator can pick whichever will suit his needs, and set up the DNS record accordingly.
