Comments on news posted 2009-07-09 12:59:12: Over the last few years most ISPs have implemented DNS redirection services, which deliver customers to an ad-laden search portal instead of a 404 when they mistype URLs. ..

USA | Thanks for "announcing" it I opted out myself. I sent an email trying to explain it to mom and dad. They won't understand most likely, but I can go visit and help them. I also offered Comcast's telephone tech support to help walk them through it.
Make money on sales and suffer with increased tech support calls and PR firms trying to save the company image...
I just tested and it is redirecting after clicking the confirmation email. It's not immediately opted out. It still needs a human to approve the request, why? | |

1 edit | Roll your own As I always say, it's easier than people think it is to run your own DNS server on your local machine.
Treewalk DNS server for Windows is free for personal use.

Treewalk is a very nice app and solves pretty much *all* DNS complaints for Windows users. An easier option for Linux might be pdnsd. It basically provides a proxy cache for dns requests. As long as it points to a clean server, you have both a clean response and the speed. I figured out its config in seconds. | |

| | No thanks If and when Comcast brings this to my area, I will be canceling my services with them.
Opt-out or not, I will not do business with a company that thinks it is acceptable to modify my internet traffic in any way. | |

I suggest you cancel them now, as well as any other residential internet connection you may have. It has been standard practice for years for any ISP to modify traffic in one way or another. DNS redirection is not even as invasive as say, Sandvine, which was employed by Comcast much earlier than this. | |
| | | | | Re: No thanks Sandvine is not even being employed by Comcast now, on my segment. And unless they're using the Bittorrent throttling mode (which forges RSTs), sandvine only throttles and shapes bandwidth, it doesn't modify packets.
If Comcast is going to set up their systems to actively lie to my home system by telling me that NXDOMAINs are actually real domains on their servers, then why should I do business with them? Why would I do business with a corporation that admits to outright lying to their customers? | |

And you seriously don't consider forged RST packets, supposedly from the computer you connected to, modifying your traffic or lying to your system? It changes the appropriate behavior of your TCP/IP stack by making it terminate the connection on the false pretense that the other end sent that packet.
Anyways, my point was almost every ISP modifies traffic in some way over their network. The Sandvine example was just to say it has been going on for quite awhile, even at Comcast. To my knowledge, Comcast has largely stopped using Sandvine in most, if not all, markets.
This, however, is not modifying traffic. It is a modification of a DNS server that they run, but is in no way a direct part of your network connectivity. It has no effect on traffic flow over the network, or the quality of service in connections to other networks. Problem is circumvented by simply not connecting to that particular server. Traffic then is normal over the very same network you have been using. | |

| | I wonder how many problems this caused Although I am not sure that this new DNS setup (redirect) is the culprit, this week my office network has had highly inconsistent success navigating the internet. I see such statements as "searching for www.www.sitename.edu.com" in the lower left of explorer window. Then a search engine will open up and finally the error page cannot connect to web page. sometimes a dns error message flashes briefly. My neighbor said that this week two businesses (that use Comcast) in his building had computer consultants in troubleshooting their computers. (My neighbor has FIOS and Macs so was unaffected). Sure seems highly coincidental to me. | |
