How do I find all IP ranges owned by Comcast?

[izanbardprince]

I want to set up a ban for bittorrent traffic to Comcast subscribers, this Comcast deal has effectively turned them all into leechers, and the situation has to be dealt with.

As long as they are able to receive packets, they won't see a problem, we need to hit them right between the eyes with a wake up call and get them to move to another ISP.

Edit: Attached the file to block all IP ranges owned by Comcast, in P2P format, with a copy of Peerguardian.

That's an a--hole thing do. Comcast happens to be the best cable internet provider for my location.

This could work both ways... since comcast users are still able to seed to each other...

but again, its not our fault! i personally seed everything i can to a 2.0 ration but its not my fault that comcast banned us from seeding, i cannot get any other isp and i would see if i was able too.

[misfitpierce]

I can still seed to ppl encrypted and do so. I changed default port which may be a good idea... Mine is at 5188-5189 for torrents. :)

So after digging a bit further, comcast owns a bunch of small ranges of ip addresses. Sneaky sneaky.

Go to Ip Index (http://ipindex.homelinux.net/) and on the left side search for 'comcast'

There's a lot of ranges.

Comcast has a monopoly over cable broadband here. Blocking Comcast users because the only cable ISP in their area happens to be run by jerks is a jerk move itself. I don't like this any more than you do.

[juxtaposed]

The "no seeding" thing is rolling, as in not everyone with comast can't seed at once. Some can at different times.

It will be for everyone all the time soon though.

[tbroderick]

As a Comcast user, my seeding has been unaffected. Comcast is the only broadband provider in my town. DSL is not available. I see no problem if Comcast or any ISP decides to throttle bittorrent activity during times of heavy internet traffic as long as they inform the customers that they are doing it.

[izanbardprince]

Attached a copy of Peerguardian with Comcast.p2p, it will block all IP ranges owned by Comcast.

I'm also making this into a torrent, plan on posting it to The Pirate Bay and Torrent Reactor.

And preventing people from seeding isn't?

[BoyOfDestiny]

Why not recommend this to comcast users, instead of outright blocking them?

:)

Also, just curious, to comcast users... Does their "block" work on things like bittornado, which uses random ports (10000-60000)?

[Depressed Man]

I think it has to do with the way Comcast attacks bittorenting (something about sending RST packets)

Can I block your IP?

[Dimitriid]

Comcast users I feel your pain, for years my city only had dial up ( and its a pretty big city, 5 million ) then a cable company gave you only like 500mb per month and charged 10 cents per megabyte after.

After that ISDN was offered but they ISDN company was the same as the phone company so they where interested in getting you to make more phone calls ( you only get 100 free local calls per month after that is charged ) so they always booted me off after 8 hours.

Nowadays there finally is so so connections but I am still fairly limited on my experience, when they say ADSL they really mean it: 1mb down and 128kb up :mad:

I even remember when the entire dal.net irc network just decided to ban my entire country, but then and now I've always been hunting for solutions. So do not give up, give the ssh tunneling thing a try, check satellite services, etc.

thanks, jerk. That will show us comcast users, one person using a peerguardian block list of all comcast ips. Whee.

I could give a crap, I made that list because, I personally don't want them draining my bandwidth and giving nothing back in return.

what about all the other people who are perfectly capable of giving back but dont anyway? make a block list for them?

and besides, when we are downloading our upload is fine, its only after we are done that we cant upload. (very well)

[hanzomon4]

This will only stick it to the consumer not the man.. Try looking for a way to help Comcast users circumvent this BT seeding "block".

There has to be something you can do, this isn't 1998, DSL is practically everywhere, fiber optics is gaining popularity, broadband over power lines is being tested in several cities, and even if you're out in the stix, there's still satellite.

Also, there are many ISP's still supporting ISDN.

I too once had Comcast, the service was terrible, sometimes the internet service would go out, with no explanation, over several city blocks, and Comcast wouldn't fix it for hours, if not a day or two, it was about twice as expensive as my DSL line, and about half the speed.

Or do this (http://thaking.net/pages/comcast-fix/).

[rivalarrival]

I'm thinking more from the viewpoint of webmasters... It shouldn't be hard to target Comcast traffic to your website/blog/etc with a message of what's going on and links where Comcast customers can complain.

The more dedicated among you could provide links to competing ISP's in the user's region.

It can't be hard - if I believed the ads I see, my town's population is 80% 18-26 year old hot, semi naked chicks looking for me. (Wish one of them wold find me already...)

Thanks!! You didn't get them all, but I can probably manually find the rest.

BTW, if anyone is interested, I used this blocklist converter to convert this into eDonkey format for use with uTorrent:
http://www.bluetack.co.uk/convert.html

For all the Comcast users, sorry you have to get caught up in the crossfire. But I agree with the original poster.

I'm passing this along to several of my friends, so there's going to be at least 20 people using it. Hopefully it catches on.

[LowSky]

I'm sorry to all those people who are affected for doing absolutly nothing wrong, but comcast has the right to limit what you do over their network. If you don't like it switch to another provider.

[Sunflower1970]

Comcast may have stopped their throttling of bittorrent traffic, according to one user:
http://consumerist.com/consumer/comcast/comcast-ceases-throttling-traffic-after-negative-ap-story-314759.php.

Amusingly, this has made it all the way to Congress... http://valleywag.com/tech/politics/congressman-tells-comcast-to-play-nice-and-share-315109.php

Comcast isn't the only broadband provider who does something like this. So does Time Warner...Not bittorrent traffic that I know of, since I don't use it...if one downloads a large item...such as a ton of different ISO's for different distros, which I have, they'll reset my modem to try and stop the download. Interestingly enough, the resetting of my modem used to happen every few hours when using Windows, whether I was downloading something or not...when I switched to Ubuntu, the restting happens only every few days, or sometimes I can go weeks before it happens....but it sure is annoying when one is trying to win an auction on Ebay and in the last minute or so of the auction all of a sudden the modem goes out for a reset....AAUUGHH!

[agurk]

Blocking Comcast is the apropriate response to such behaviour and it has worked in the past, for example when thepiratebay.org blocked the Perspektiv network. If you have no other ISP in your area but Comcast, just hang in there until Comcast caves in. And they will.

[jc87]

Why don´t you change to other p2p tools that benefit thoose who share?

I know it sucks, but all around the world there are crappy ISP´s that make users leechers against their will, for instance i´m Portuguese and my ISP package (netvisao) is the following:

Download speed - 2mbps

Upload speed - 128kbps

Traffic limit - 13 gigabytes

Happy hour - From 01:00 am to 09:00 (no traffic is counted during this period)

I pay for it about 25 euros month, and extra 1,75 euros for each extra 100 megabytes

I would seed more if i could, but except for P2P i´m currently happy with my ISP (good gaming pings and network stability, wasn´t always like that in the past but improved a lot)

If they increase upload speed in the next upgrade i will seed more, otherwise i will only share the litle i can in the moment ( in Portugal ISP´s suck a lot)
