Mediacom Redirects AGAIN

Click for full size
I have tried everything to stop the Medicom redirects and even when I successfully reach the Preferences page and change it (again) the redirects come back quickly. Now I can no longer reach the preferences page, I get this new "locked" vs preferences sever offline (for weeks?) page. Any ideas/help??

Can you tell me how you got to this page?

Click for full size
Type in any bogus web address, like helpme.what and hit enter, the browser (every one I have tried) goes to the redirect page, the upper right side of the redirect Mediacom page has the usual Why Am I Here? link, click that it takes me directly to the page I posted above. Why is the Mediacom default to Force a redirect to Mediacom which we can only stop by opting out, yet opting out does not work, and now there is not even access to any preference to opt out.

Hello Veloz,
Thank you for your patience. We have a ticket on this issue already and it is currently being investigated. As soon as we have a resolution I will let you know here.

The simplest way I can tell you to stop this from happening is to change your DNS server.

Here are the instructions for windows 7. I'm sure you can google directions if you have a different operating system.

»windows.microsoft.com/en-us/wind···indows-7

Change your DNS server to (primary) 8.8.8.8 and (secondary) 8.8.4.4. These are the google DNS servers. Changing this will prevent you from ever seeing the mediacom redirects ever again.

However you should also be forewarned that doing so will also prevent you from seeing other (possibly important) redirects from mediacom like your usage alerts/warnings etc. Do so at your own risk.

But, if you absolutely must be rid of the mediacom redirects this should do it for you. This is exactly what I did to escape them myself.

I gave up trying to turn off Mediacom NXDOMAIN DNS redirects after months of "Tier 2" checking into it (from 2013-01-07 to 2013-09-15 from the DSLReports IM logs between MediacomChad and me) and turning up nothing.

I experienced the following tonight:

- Open a web browser and go to a nonexistent hostname (e.g. oaishefgaosiehgaowiehf.com)
- Arrive at a page (»assist.mediacomcable.com/mediaco···iehf.com) with the note "We did not find results for: oaishefgaosiehgaowiehf.com. Try the suggestions below or type a new query above"
- Click on the "Opt Out of this Service" link at the bottom of the page
- The first time I clicked the "Opt Out of this Service" link tonight, I was taken to the regular "Enable/Disable" typo redirection page, however the top of the page included a new statement along the lines of "Mediacom has partnered with Yahoo and other groups on the Internet to [help with typos]. To opt out of this service, " (paraphrasing, sorry).
- I "clicked here" and was taken to "Your Preferences Are Currently Locked: The preference settings for your IP are currently locked either because you are not allowed to set preferences or because the preference server is currently offline." »search.mediacomcable.com/prefs_locked.php
- Now every subsequent time I click on the "Opt Out of this Service" link I'm taken directly to the "Your Preferences Are Currently Locked" page

Would love to get this fixed--just IM'ed my account number to MediacomChad.

Note this could have a negative impact with some content delivery networks (CDNs) that deliver media (mostly video) from large content companies such as Apple (iTunes), Netflix, etc. Different DNS servers are given different DNS records so your computer/device is pointed at a "nearby" CDN server for faster service.

Actually, I've noticed nothing but a POSITIVE impact with CDNs from this change. Using Google DNS servers has actually (vastly) improved the performance of youtube, twitch, hulu and netflix for me. I can only assume that Google has better (or faster) peering connections which allow me to receive data from these sources easier. I'm no network admin or anything, so take my experience with a grain of salt.

That is not how the internet works. DNS is like a phone book, not the phone line.

As for OP, I would use Open DNS: 208.67.222.222 and 208.67.220.220, and stay away from Google's, as cool as it may seem.

simplified. (i.e. im no network admin). you want to go to google, you type in google.com in your address bar, the browser then requests the IP address from the dns server, the dns server replies with an address. your browser then goes to the address via what ever "path" the ISP selects. the dns can not specify a path.

i.e. you want to call doe, you look up their phone number in the phone book, you pick up your phone and dial, you have no control over what path the phone call takes, the phone company does.

You get some pretty cool filtering options you can do, even though I don't use them anymore. There is also phishing/mistyping protection built in, which is great for my parents. I've never had it go down, either.

Sure Google has their "phishing protection", but it is complete garbage, many times I've seen it block legitimate websites for no reason at all. Also I don't want Google tracking EVERY website I go to.

As for ping times, Open DNS is 35ms, Google's is 28ms, and Mediacom's is 30ms, so no noticeable difference with any of them.

My problem with Mediacom's DNS servers is not their response time, but their DOWN time. During the first several weeks of my service with Mediacom their DNS servers were down repeatedly and for hours at a time, making my internet service with them useless.

Hence my switch to using Google's DNS servers. Since the switch I have not noticed ANY downtime at all.

As far as my experience with faster browsing of youtube, netflix etc since switching DNS servers - perhaps my perception of increased performance relates to increased DNS record lookup speed. I can't explain it as I've mentioned I'm not a network admin, but this is my experience. Take it as you will.

Additionally you'll also notice that if a site switches its location (such as it might when switching host providers) that the update of that DNS information will happen much faster to google's DNS servers than it usually will to mediacom's.

Yes, but the assumption there is that there's one source/server for a particular piece of information, whereas NetFlix/Amazon/Apple have many many servers.

Think of it this way--if one asks directory assistance for McDonalds, there's one a mile away and one in Boise, Idaho. They both serve the same cheeseburgers and the same same soft drinks. However the cheeseburger and drink will be obtained much more quickly by going to the McDonald's one mile away rather than Boise.

In the same way, there are local phone books with information optimized for the people in that locale. One could check a (theoretical) "national" phone book for McDonalds, but the local phone book will give local results. If someone checks a "national" phone book (OpenDNS, Google Public DNS) they're going to receive valid yet unoptimized results due to the lack of geographical information. In the same way, Amazon/Netflix/Apple may try to provide Mediacom's "local" DNS servers with "local" servers for streaming video.

Does it work perfectly? No. In fact I'm not surprised it may have the opposite effect in some cases, but it can have a positive effect. If Netflix can make a customer's video stream that much smoother with a "local" server they may choose Netflix over a competing service.

A related idea--Netflix's "Open Connect Content Delivery Network": »www.netflix.com/openconnect .

This problem has been going on for years and it never gets fixed. I was getting the "preferences are locked" page sometimes, but recently I have not. I have to disable the redirects about once a week. I don't think they will ever fix it.

Mediacom doesn't have the leverage to make Netflix pay.

Not from where I sit. I can't test the Mediacom DNS servers; too lazy to identify them as I am not an MC customer. But OpenDNS is dead last, after my ISP, Google (pretty much neck-and-neck), and Level 3:

Oh yeah, I totally forgot about »www.grc.com/dns/benchmark.htm . I remember using that a few years ago to see what the best one was on my Sprint connection, and turned out to be a Sprint one . . I just ran this on my Mediacom connection, and tested my "top 50" I created. Looks like a couple AT&T DNS servers are the best, which makes sense, sense the traffic goes through AT&T fiber to Chicago. Other top ones were "Internap Network", Sprintlink, and Verizon.

I recommend everyone try using this tool if you do not need any extra DNS tools. The AT&T ones came out at 0.012, and Sprintlink and Verizon were at 0.014, Google DNS made my list, but ended up being at 0.036.

The GRC tool is good, but here is another benchmark tool: »code.google.com/p/namebench/

Remember that if your own router (default gateway, commonly 192.168.x.1) appears in the list, that means your router is doing DNS proxy or masquerading, which is slowing you down, and makes you more likely for rebinding attacks, I'd strongly suggest you disable it.

If for some reason you like your ISP's DNS servers, but want to remove there "guide" page there are two other work-around's 1) In SimpleDNS Plus use the Ignore DNS Request Plug-In or Fixed IP Address Plug-In or 2) In DNS Redirector block the domain of the guide page - you could sinkhole the guide page to an invalid IP, or your the IP of your own webserver - to host just a blank page, or a page that says "ISP guide page would have appeared here" perhaps with a Google search bar instead.
