Hello Brough, Very well spotted!! :-) I finally fixed a problem in my analysis programme which was miscounting the extended range of 32-bit ASNs (those from 65536 and above). It wasn't counting them at all in fact, something spotted by one of our industry colleagues a couple of months back. So the jump is caused by that. Misery for me now is I have to go back through a few years of daily reports and figure out when I made the change to cause the breakage. And rerun everything (sigh). The other bonus of the fix is that I'm dealing with 32-bit ASNs properly now - I'm catching the 65536 to 131071 range as bogons, and also catching any origin ASNs from above 458752 as bogons too. Thanks! philip -- Brough Turner wrote on 4/2/17 05:35 :

I've seen the number jump a few or a dozen in one week, but nearly 1000 in one week?? What am I missing? Thanks, Brough Brough Turner netBlazr Inc. – Free your Broadband!
