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 : > On Fri, Feb 3, 2017 at 1:02 PM, Routing Analysis Role Account < > csc...@apnic.net> wrote: > >> Transit ASes present in the Internet Routing Table: 7547 > > > Last week there were 6561. > 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! > Mobile: 617-285-0433 <(617)%20285-0433> Skype: brough > netBlazr Inc. <http://www.netblazr.com/> | Google+ > <https://plus.google.com/102447512447094746687/posts?hl=en> | Twitter > <https://twitter.com/#%21/brough> | LinkedIn > <http://www.linkedin.com/in/broughturner> | Facebook > <http://www.facebook.com/brough.turner> | Blog > <http://blogs.broughturner.com/> | Personal website > <http://broughturner.com/> >
