What about the many T-1s that have an rDNS entry containing "DSL".
Somebody is paying for a T-1, has a netblock, and doesn't have reverse zone delegation? And these T-1 people are out there in the 1000's, or are they anomalous blips in the vast population of T-1's?
Anyway, AOL is blocking, or going to block, by network/netmask, not by PTR hostname, IIUC.
( Since I would like to do the same but don't have list of those networks/netmasks, I inspected the connection log lines and saw that the network operators were using labels and subdomains for their PTR hostnames that were amenable to regex pattern matching. )
And does the rDNS containing "DSL" in and of itself constitute a dynamic dsl circuit?
I don't even worry about the "dynamic" part. There is so much horrendous abuse from DSL and cable lines, the static vs dynamic issue is in the noise.
There is such a thing as SDSL which actually works quite well.
I had one, but it could only go 192/192.
>There's a war on. Don't stand where the bombs are falling. I'm not standing where the bombs are falling. This problem is not affecting me (currently). My concern is what happens next. Enough erosion causes the cliff to fall! Will I be swept up in the next policy decision that becomes the standard?
Who knows.
>>2. This goes against what most of us believe as "presumed innocent until >>proven guilty".
>yep. Dynamic networks are guilty, IPs without PTR are guilty, for AOL (and >all of us) of massive mail abuse. What about the innocent admins that have static IPs, but are classified with dynamic IPs? Do you also agree with DSBLs listing entire class C block when a few IPs in the block are spammers?
yes. but don't take it personally. When an network operator allows abuse to originate and persist from his networks (he is making at least the subscriber fees, and maybe additional $$$ for harboring the spammers), then enlisting nearby legit, clients by blocking at the network level, in policing the recalcitrant operator is justifiable. The legit clients complain about their pain of being blocked to the operator, increasing his pain. If the legit subscribers then cancel, the pain to the operator increases more.
>AOL knows best for themselves. People can believe anything they want. And you honestly don't think that AOL will "spin" this? Len, there is a new thing that came out about three centuries ago, call politics!! :)
Why should they "spin" anything? Do you doubt that AOL has a horrendous spam problem? Do you not believe them when they say "we are doing X to reduce our spam problem", they are spinning that they are really trying kill off ISPs and pick up their customers? Do you not think they will lose big $$$ if their subscribers leave due to AOL's ineffectual spam controls?
The press is a powerful thing.
yep, look how shrub spun Iraq as "threat to USA"? ( The news corps, wanting favorable treatment from the shrub's FCC/FTC to cartelize, haven't yet yelled the Emperor Has No Clothes. And I don't think they will.)
>relay your outbound through your ISP, and move on. I don't need to. I'm not impacted by this.
again, you = anybody with the problem.
>networks. You don't think they want the extra customer base? You think the board meetings include the words "we have enough customers"?
Every business knows the cost of creating new customer is MUCH higher than retaining current customers. How many 100s of 1000s or millions of AOL clients leaving for HotMail or MSN do you think AOL can tolerate? (There is already noise about T-W selling AOL ISP as a money loser.) If AOL is perceived as having a "spam problem" and Hotmail/MSN doesn't.... AOL has to reduce their spam problem just to retain current subscribers (and reduce AOLs current costs of fighting spam).
