Chris/Nanogians,

Block hijacking appears pretty popular nowadays.

yes :(

One member of our local exchange had a request to advertise this unused block: 160.122.224.0/20. It appears it was also a UBE related hijack attempt, which failed ofcourse.

This was a block who's contact info has been marked as invalid... :( so this is likely hijacked and ARIN should be or has been working on it...

With so many defunct networks over the last 5 years, do the TLAs attempt to recoup blocks, based on length of time out of the global routing table?

I do not believe that this is the case, but I'm not working for ARIN and don't know for sure :(

Any other systems in the works/place to expire invalid blocks quicker?

Ask ARIN ? I really don't know. :(

Regards, Bill R.

Ok, before someone else gets saddled with this problem... ARIN pulled the 157.156.0.0/16 from their database. Spam-afficienados would recognize this as 'VMX Networks'. ARIN has decided it seems that 157.156.0.0/16 is not actually registered to the modern day VMX, so, if they come visit your sales staff for a connection using this ip block (or 134.33.0.0/16 which is also invalid currently) you might want to carefully consider accepting the routes :)
