if you were my neighbor, and you had a gangly tree overgrown into my yard that i took an issue to, i think i would most likely call or talk to you personally about the issue, rather than carry out some agenda by sending pictures of it to the community newsletter, saying "hey everyone look what this guy is doing" On Mon, 29 Oct 2001, Adam Rothschild wrote:

There are some particularly entertaining "bogons" (well, in my mind) in the non-abbreviated version, including:
$ /usr/local/rancid/bin/clogin -c "show ip bgp regex 3967_" border1.nyc1 > exds-routes $ grep "/32" exds-routes |wc -l 27 $ grep "/31" exds-routes | wc -l 2 $ grep "/30" exds-routes | wc -l 293 $ grep "/29" exds-routes | wc -l 114 $ grep "/28" exds-routes | wc -l 269 $ grep "/27" exds-routes | wc -l 220 $ grep "/26" exds-routes | wc -l 275 $ grep "/25" exds-routes | wc -l 312 $ grep "> 10." exds-routes *> 10.255.253.34/32 x.x.x.x 0 3967 i *> 10.255.253.35/32 x.x.x.x 0 3967 i *> 10.255.254.34/32 x.x.x.x 0 3967 i *> 10.255.254.35/32 x.x.x.x 0 3967 i

The above is related to ongoing renumbering of former Globalcenter customers. If you watch you will see a difference each week.
$ grep "> 10." exds-routes *> 10.255.253.34/32 x.x.x.x 0 3967 i *> 10.255.253.35/32 x.x.x.x 0 3967 i *> 10.255.254.34/32 x.x.x.x 0 3967 i *> 10.255.254.35/32 x.x.x.x 0 3967 i
You were seeing this in NY only. This was related to ASN conversion of former Globalcenter datacenters. It is resolved.
Can a brother get some prefix-filters?
Also, a much more pointed effort is being made to reduce routing table bloat. This was started at about the time of RIPE 40. If you watch you will see a difference each week. Regards, Sharif
as has been said in the past... this is being addressed. getting customers to renumber is, well, not a trivial task. On Mon, 29 Oct 2001, Adam Rothschild wrote:
