| A request to Charter Cable admin staff
If it is possible could you go over to: »www.spamhaus.org/pbl/index.lasso and enter in all of your dynamic ranges. That would begin to stop the onslaught of infected computers on your network spewing out spam and help admins to keep their users email boxes free from spam.
Thanks,
Neil |

| Ah...actually could you please not...some of us have mail servers that already have enough send and receive problems, we don't need that extra crap telling other peoples servers to reject us.
I got a better idea, monitoring your network for the various worms/viruses causing these problems is trivial. Detect the problem machines and cut off their network access. |

| Since the various worms/viruses are coming from computers located on charter's network I politely asked that Charter give a list of which IP's are dynamic (residential) so those that want to can block IP addresses that shouldn't be sending email anyway. Does Charter allow residential customers to run their own mail servers?
I am just trying to help those outside of Charter keep their networks from being abused by insecure computers on Charter's network.
Listing only the residential servers shouldn't effect those that are on a business/commercial IP address. |

Belleville, IL | I highly doubt charter is going to give you a list of these ips. Machines are compromised daily so they would have to update the list quite frequently and i doubt that would happen too. |

Actually individual IP's wouldn't be submitted, just the IP ranges. So it wouldn't matter on the changing amount of hijacked comupters - it's not on an individual basis.
There are other blocklists that block the dynamic IP ranges of cable, DSL and dial-up internet services. Typically, mail isn't sent from your IP address so it shouldn't be of concern if your IP address is listed on a BL. |

actually i am having the opposite issue. for whatever reason, charter gave me two static IP's in their dynamic pool. i was having a lot of issues with charter business mail filtering out important emails as spam while delivering viagra ads and penny stock spam.
recently moved one domain to godaddy, and have been having a problem with them not sending/receiving because our static IP is in charter's dynamic range. had charter place an RDNS pointing domain name to IP in hopes to correct that, but still have spamhaus issuing blocks off and on because of where my IP is parked. |

I don't think you're gonna find any admin that visits this forum that will submit any information over to a third-party without Corporate's approval, and I just don't see that happening either [Corporate's approval].
There already is an established method for reporting abuse by a Charter customer:

| I am not asking for it myself. They can submit it to spamhaus, as many other domains have done. This isn't the first instance of requesting dynamic residential domains so that others can block a increasing problematic way of sending spam. Charter (and other large internet services) don't have the staff, time, budget to keep on top of the insecure boxes on their networks. This would reduce a lot of the time and hassle or at least it would keep the widespread blocking of their networks from happening due to the inaction of providers to police their own users. This would be a "win" in the P.R. department for Charter to have less people griping about all their insecure computers on their networks. sending out spam. All it takes is submitting data to spamhaus. Sadly, corporate insecurity and paranoia gets in the way. (along with the quest for the almighty $$$$$). I guess if Charter doesn't want to do this, unlike other networks then they are saying "deal with our customers insecure boxes" and "eat your spam/just hit delete". |

| I was referring to Spamhaus (third-party).
You could try calling the corporate office during normal business hours and see if you can get in-touch with someone that would be receptive to your suggestion.
I guess what I'm trying to say is that requesting such action in this forum probably wasn't the best avenue since you probably won't find anyone here that is authorized to follow through on your suggestion. |

If you are a business customer issued a static IP on an rBL by mistake you can call in and open a ticket 800 314 7195. It is possible for Charter to get it delisted if it hasnt been SWIPed to you. It's probably just a matter of an incorrect PTR. |

Oh, sorry about that one. I was trying the "easy" way and hoping someone had some "connections" to get something done. I actually thought about taking the official path of contact but I wanted to test the waters first. Thanks for the reply. |

Sorry about the confusion. I am actually on another network, trying to get an accurate list of dynamic IP blocks for charter so that I can block the infected computers from being able to send spam to the networks that I filter email for. Charter has a lot of customers in my area, so i can't just make a wide listing due to the possibility of blocking customers/clients. I was just hoping that someone at Charter would just go to spamhaus and enter in their dynamic ranges. It would allow those that use spamhaus' feeds to be able to block ip ranges that should not be sending email anyway. |

Louisville, KY | all our residential IPs should have "dynamic" listed in their PTRs so that they cant be used for mail relay and be listed on rBLs. Some do slip through the cracks unfortunately. |

No problem.
I totally see your point, but, it's my opinion that you'll probably have a better chance by going the route I suggested. Unless, of course, there's someone out there that has a better idea and has those high-reaching connections  |

The best idea is that residential ISP customers shouldnt be their own MTA. You should be smarthosting through their smtp servers.
Static IP customers shouldnt be on the same netblock as dynamics anyway.
A little extra hassle for the 0.1% of people who want to run their own MTAs and can do it safely is more than worth the reduction in spam from a kabillion jacked up hosts flooding the world. |

| It astounds me time and again how the internet has changed over the years. What people will now consider acceptable. Or stated another way, how the perspective of how people expect the Internet to work...the model it should work under has changed.
I suppose its because I come from the old school. I still believe in the original concept. The Internet is not and should be a strict client server model. It was concieved of and should remain a peer to peer model. If I wish get a connection through charter or whoever, I should be able to use that connection for whatever purpose I wish, without having to involve anyone else in the matter. If I want to run my own mail, ftp, web, bittorrent, etc server its none of anyone elses business. I pay Charter for the Bandwidth to get my machine(s) connected, end of story. Their end of the bargin is to provide me the connection and keep the network functioning. As long as I am not doing anything to damage someone else's machine(s) on the network, spewing Virus and such...our relationship is concluded. I or someone else is spewing virus/worms etc and infecting other machines thats the point in the relationship that Charter should get involved, and cut off that one person's access.
It is my further belief that they should being doing quite the opposite of the original post. They should be working to police and clean up their IP ranges, and get them UNBLOCKED by outfits like spamhaus and the like, so users like myself can go about our day like proper internet citizens, using the net for its true peer to peer intended purpose. |

| You're so old school that you forgot to read your residential service agreement, which forbids you from running a server on your connection.
Doesn't matter to me, though. I don't work for them anymore and I am not serviced by them either. So, happy serving I guess.  |

We have millions of IP address on our networks, and thousands upon thousands dynamic IP blocks alone. What you are asking would take weeks. Just hire someone for your company who understands how to use a firewall and take of it on your own is your best bet. |

The TOS is crap that would never actually stand up with seriously challenged. I had a lawyer look it over once, and he told me quite simply "ignore it, its unenforceable, if they ever cut off your service, and pointed to the TOS/AUP you'd own the company when we were done with them."
For the mpost part I do very little other that run my mail serve on my connection the web, FTP, shoutcast are mostly there as a form of protest...or perhaps civil disobience. |

I am actually doing that myself. I am trying to do my best to discriminate between business/static IP's and residential/dynamic IP's from DNS lookups. Charter's host names don't really give a good representation of what is residential vs business. I really don't want to start blocking whole IP ranges of Charter. If that is what it takes to keep the email abuse from flowing from Charter's customer IP ranges that is what I will do. The spamhaus solution will go a long way in keeping the abuse complaints down and reduce the overall work of Charter's admins. I guess the admins would rather play whack-a-mole with infected computers rather than provide a list of IP's that should never be sending emails in the first place.
Of course I understand the this is my network and you won't tell me what to do type of attitude, it is standard with today's admins/providers. Sadly a solution is provided yet blown off due to it's too much work .
Oh well, at least I tried to help prevent email abuse coming from Charter and protecting those that choose to use spamhaus' lists to prevent that abuse.
I noticed something after reading your reply. It is very scary that you (Charter) doesn't already have a breakdown of static vs. dynamic IP blocks already. I guess when a business calls Charter and asks them for one or more static IP's you (Charter) just goes out and finds the next available IP address with no concern about keeping static and dynamic IP's apart for technical, QoS and bandwidth management reasons. That is really scary if it is true. If it is that way it would explain a lot about why you (Charter) can't get a grip on the infected computer epidemic. |
