[Cable HSI] DNS servers are messed up.

The Mediacom DNS servers are messed up. When I go to microsoft's "bing.com" search engine and search for "sears cashback" and select the first link, I keep getting a Mediacom error page "We did not find results for: . Try the suggestions below or type a new query above". My Mediacom assigned DNS: 97.64.187.150 and 74.84.119.153

If I change my DNS servers to 204.127.203.135, and 216.148.225.135; it works fine.

The first part of the URL is 0.r.msn.com which returns a ip address of 207.46.118.158. (name resolves to r.msn.com.nsatc.net).

I don't understand this. Using the Mediacom DNS should only affect the IP address returned but it is preventing the long URL from loading. This seems like Mediacom DNS request is triggering some kind of web proxy to return the error for the HTTP request.

Can others reproduce this behavior?

Did anyone try this search on bing.com with Mediacom DNS?

Works fine. But I opted out of the search redirect.

I am opted out of search redirect too. This is not search redirect, because the ip address resolves.

theres a thread around here some where about search redirect hijacking 404 error's. so just because the IP resolves dosent mean a thing when it comes to mediacom.

What you are seeing is Mediacom taking over for 404s (page not found). Supposedly, you can turn this "feature" off, but many have an issue with it staying off, or even getting it turned off.

I was able to turn it off, then we had some "maintenance" which resulted in a new IP address. After that point, the Mediacom preferences shown I was opted out of Mediacom's 404 redirects, but I was still getting Mediacom's 404 redirects.

Why would using Mediacom's DNS server give 404 errors? If the IP address is the same, the only explanation is that Mediacom is using a DNS request to trigger some sort of proxy intercept of my actual HTTP request.

Mediacom's system is pretty messed up if it can't even access bing.com (Microsoft's search engine) URLs.

Any comment from Mediacom head-end employees on this one?

A normal Mediacom HTTP 200 or 404 intercept returns:
assist.mediacomcable.com/mediacomassist/dnsassist/main/?domain=fghals.com

but for the long Bing.com url the intercept is returning:
assist.mediacomcable.com/mediacomassist_ie/dnsassist/main/?domain=

Notice the domain= is not filled in and also notice that the new url has "mediacomassist_ie" instead of "mediacomassist".

This faulty redirection is something new. I have never seen anyone else report valid sites not working (returning Mediacom pages) with Mediacom DNS.
