RE: [nznog] IP address allocations and geographic areas
Unfortunately there are some in the U.S. that do block all APNIC space, mainly due to the amount of spam originating from China and Korea. Personally, I think putting Florida into its own address range and null routing it would have a far greater impact on the global spam levels :-) I'd suggest emailing them from an address that isn't blocked and point out the error of their ways Cheers, Gordon

This is really strange since all the figures I have seen suggest that most of the spam originates in the US. They don't see this, of course because US address space is smeared over the whole address space, where as APNIC address space is concentrated in just a few /8s. I can remember a few years ago when every school in Korea has a hacked linux box that was being used to attack everyone else that several US companies blocked 210.0.0.0/7.

Plus there is a lot more legitimate mail coming from the US to the US, where as blocking APNIC results in fewer false positives for a lot of US companies - not that I think it's a good idea to block like this. According to Spamhaus, MCI are currently the worst ISP and the US is the worst country for spam - http://www.spamhaus.org/statistics.lasso I would go further and say it's a really bad idea to use any form of blocking which is not being actively maintained and monitored for false positives. cheers, Jamie -- James Riden / j.riden(a)massey.ac.nz / Systems Security Engineer Information Technology Services, Massey University, NZ.
