FYI: [Argus] 12.231.155/24 is 'hijacked' by anomalous origin 'AS13490'
by Yang Xiang 22 Mar '12

22 Mar '12

Hi, Just now we found a hijacking, as shown below. Is it a real prefix hijacking, or a false alarm made by us? Hope someone in this list, maybe the admin of those ASes listed below, can give me a reply :-) The feedback can help us improve Argus and provide more valuable information.

Is it just me? Or do these Huawei wireless APs look like Ruckus APs? http://enterprise.huawei.com/ilink/enenterprise/support/documents/base-netw… Looks specifically at the A603DE and WA653DE. Even the GUIs look very similar. -- Also on LinkedIn? Feel free to connect if you too are an open networker: scubacuda(a)gmail.com

Microsoft/Hotmail forgot to set reverse DNS pointers?
by Michiel Klaver 22 Mar '12

22 Mar '12

Today I received some notices about Hotmail users who couldn't send e-mail messages to various receipients due to spamfilters blocking them at the receiving mailservers. Seems like Microsoft/Hotmail staff forgot to set some reverse DNS pointer records: Diagnostic-Code: smtp;450 4.7.1 Client host rejected: cannot find your reverse hostname, [157.55.1.150] (Verified this using various public DNS servers, to exclude potential local issues) Anyone here who has proper contacts to give them the clue-bat? -- Michiel Klaver IT Professional

spammers trying to "lease" IP space?
by Michael Holstein 21 Mar '12

21 Mar '12

I know this tactic isn't exactly new .. just thought I'd pass this along. Text below is exact with exception of our ARIN information and ranges (which any of you could figure out anyway). Cheers, Michael Holstein Cleveland State University --snip-- Description: ABC Widgets *Greetings, NOC or IP Admin at (our ARIN NetName)* ** We would like to Lease or even Purchase some of your IPv4 Ranges like (our/16) “Why do You want to lease our IPs?” Very Simply: Our Business is the delivery of Opted In Marketing Email. The key to this business is good stewardship of IP assets to ensure deliverability, and even more importantly; *Sustainability. *Many of our IP leases last years due to our investment in our network before we ever even mail. As a result it takes Several months before a subnet is profitable for us after recouping our initial infrastructure expenses. So to Hit and Run simply does not make good business sense, after all maybe if we are good to our word you will offer us additional IPs! ** there are two core requirements in any Major League Mail Campaign ? a. _Having a solid list_ with real recipients and records to prove their Sign up is vital to delivery but also to settling any complaints registered with an ISP. b. _Using Multiple IP addresses_. If having a good list is a good defense then using Multiple Static IP addresses is a proactive measure. ISPs, Backbone Carriers, Software Makers, and more all use (among other means) Algorithms to shape traffic across their networks and to their clients. Using an MTA to spread our traffic across thousands of IP addresses from then thousands of ‘C-Blocks’ we mitigate the footprint of our traffic originating from any one network range. ?/It should be noted here that this email is a Request for Pricing (RFP) and its recipients have in no way requested it, they have instead been identified through research, and therefore this email should not be thought of as characteristic of our normal mailings./ Precision Management of Texas (USA) offers on-demand solutions for brand marketers and website promotion chiefly through email marketing. Currently PM is seeking to expand its network capability both overseas and here in the US with the addition of several points of presence (PoP) in geographically diverse locations. Precision Management makes no attempt to conceal identity or intentions as a show of good faith on our part that we will be good customers with an eye on building a relationship beyond this installation. It should go without saying that our use of your network will be totally AUP Compliant and any complaints will be handled in 12 hours or less. We only mail to Top Level Domain’s and do no General Internet mailing. Also i want you to be aware that we are an American Company with verifiable references who can attest to how we conduct our email business. Description: C:\Users\BLEAUH~1\AppData\Local\Temp\~ed_sb_i\~files\3.gif Description: Content Image InlinePM seeks to obtain as much diversity in the allocated IP space as possible, however the most important thing is the Subnets need to have no abuse history. We can take the IPs via GRE or BGP or other such tunneling solution to where you have them announced. Alternatively we can advertise them ourselves on our network, saving you the back-haul. As a third solution we can take a server on your network with the following specs One Virtual (or Dedicated) Server – Dual Cores 1 GB RAM 100 GB HDD? 3 Mbps dedicated - burstable to 100 Term period minimum of 6-12 months I hope you have read this far and will seriously consider this opportunity to generate additional revenue for your company.
