RE: Hotmail blackholing certain IP ranges ?
I've had the same issue with hotmail when email originates from 208.127.57.0/24. any mail sent from a server within that netblock is properly accepted by hotmail, given a queue id, but disappears and is never delivered. if anyone from hotmail has a clue as to what's going on, it would be appreciated. thanks much ... - Gabriel Kuri | Sr. Network Analyst Instructional and Information Technology Division California State Polytechnic University, Pomona http://www.csupomona.edu/~iit | +1 909 979 6363 -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jeroen Wunnink Sent: Wednesday, April 25, 2007 11:22 AM To: nanog@merit.edu Subject: Hotmail blackholing certain IP ranges ? Does anyone have a clue why hotmail is appearantly blocking certain IP ranges ? I provided a new server for a customer in his own IP subnet which is a part of a /20 we announce, but for some reason all mail sent to @hotmail.com addresses disappears. He has another server in a /24 we announce which is still part of another network and that works like a charm. None of our subnets are blacklisted in any spamfilter I can find, so i'm a bit puzzeled on what's up here. If any hotmail netadmin is reading this list, can you please check if 81.26.212.0/26 is blocked in any way (It's part of 81.26.208.0/20 originating from AS39556) According to the mailserver logs all the mail is properly accepted by the hotmail relays, never to be seen again after that.

swamp space reachability
Hi all. I have a bit of an issue. A while ago, I was issued 204.8.0.0/22 from ARIN (under ipv4 policy, 4.2.1.5 - the minimum allocation for multihomed networks). I've just gotten around to announcing it to migrate off of my PA space. In testing, I've determined that a number of networks are blackholing my traffic. I've started attempting to contact the various networks that appear to be blocking my traffic, but that's not going particularly fast. My question: Has anyone else who has received a small allocation from ARIN had this happen to them? If you'd like to look and see if you see my announcement, I'm announcing 204.8.0.0/22, as well as the four /24s that make it up (the deagg is temporary and to see if it helps, I'm well aware that aggregating is preferred). My AS is 30233. Thanks! Gabriel P.S. To those of you who will be at NANOG 34 this Sunday, I look forward to meeting you guys. -- Gabriel Cain www.dialupusa.net Senior Systems Administrator [EMAIL PROTECTED] Dialup USA, Inc.888-460-2286 ext 208 PGP fingerprint: C0B4 C6BF 13F5 69D1 3E6B CD7C D4C8 2EA4 2B08 1C6D The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather in a lack of will.

They have the responsibility to do what is necessary to correct the vulnerabilities in the systems they chose to run. Most of them don't know any better than to run what they've got.

This is akin to driving a pinto, knowing that it's a bomb, and expecting your local DOT to build explosion-proof freeways. Your analogy is flawed. The problem is, most people don't realize that: 1.) Windows is as flawed as it is, 2.) That there are real alternatives. But, I suspect, this has gone far off the topic of Operations.

Unique AS
Hello All, First of all, forgive my English writting please! I work for an Internet Carrier in Argentina which is in process of reorganizing its regional operations. We are also serving in other countries in South America. We currently have one AS per country and we are looking forward to migrate to a unique AS for all the organizations. Could anyone describe pros and cons of having a unique AS for this kind of networks rather than having one AS for each country. Regardless of the cons, we are facing migration process anytime soon, so I would appreciate very much to get more pros than cons to include in my papers which are almost finished! I would also be glad if you share your experience about this migration process. That is the real value of your answers. Thanks for your time. Regards, Gabriel.

Cross country networks, and data replication... Questions... :-)
Hello all. --- Where we are --- Currently, I've got a single site, colocated on the East Coast. Currently, I've got two NetApps at that site, one serving as a mailspool, the other serving as a location for web documents. This system works via NFS to a fair number of mail and web servers, and it's running happily. --- Where I'm going --- What I seek is some help on implementing a second site, and the link between the two. The sites will be more or less the same in terms of the equipment in them, or so I hope. I want to be able to have the changes made at one site replicated to the other site transparently. That is, if I update a file at site A, I want to be able to see the changes at Site B in a reasonable period of time (i.e., short), and without having to manually move data around. I specifically want to do this for allow both sites to offer the same mailspool, so that customers can check their mail at either site. I am in the planning phase of bringing up a second site, and at this site, there will be more web servers, and more mail servers. There will also be an additional netapp for each of mail and www. Between the pair of mail netapps (and to a lesser degree, the www netapps), I want them to replicate changes to the other one. That is, if a file is removed on Mail.NetApp A, it should also disappear on Mail.NetApp B. And if a file is created on netapp B, it should also come into existance on netapp A. Bidirectional updates. My current setup consists of Linux and FreeBSD systems, and F740 NetApps. And yes, there is a lot of pressure to stay with the NetApps. Any hints, or advice will be much appreciated.

IWon/Excite mail admin...
Hello all, I've been trying (rather unsuccessfully) to get a hold of iwon/excite. They're blocking my mail servers (safepages.com domain), and I'd like to talk to them about it. My question: Does anyone have a NOC or mail admin contact for Excite/Iwon that they would be willing to share? (And to reciprocate, if anyone has been getting spam from my domain, I'd love to talk about it so I can shut down offending user.)
