Can't this kind of thing, once posted, be handled off-list unless it's really worth discussing? Sorting through the barrage of daily nanog mail is hard enough without useless clutter of this sort. Maybe an IRC channel or something dedicated to this sort of minutae would be more appropriate? -t

Burt just raised this expired draft in the IETF policy working group. He is intending to make this an Informational RFC... so, if folks think this is important, they might want to comment to Burt &/or the Authors. ------------------------------------------------------ Requirements for Configuration Management of IP-based networks ... 1.1 Motivation, Scope and Goals of this document Over the past several months, a number of IETF working groups have introduced new technologies which offer integrated and differentiated services. To support these new technologies, working group members found that they had new requirements for configuration of these technologies. One of these new requirements was for the provisioning (configuration) of behavior at the network level ... -- --bill

no list would be complete without JEEVES written by Paul Mockapetris Of course, we need to find a working TOP-20 machine. IBM had a 370 version of DNS, and I believe Tandem had a non-BIND version of DNS.

Considering that they have a positive revenue model (vs TLD registries that don't, or have negative revenue models) I would suggest that they pay for it and help support ISC/BIND.

/24's run amuck?
by Richard A. Steenbergen 07 Feb '01

07 Feb '01

I noticed something interesting the other day... /24's seem to be contributing to the majority of the internet routing table today. Here is the breakdown right now as viewed through GlobalCrossing transit (the view is consistent from many other sources): Length /8: 23 Length /9: 4 Length /10: 5 Length /11: 10 Length /12: 32 Length /13: 59 Length /14: 194 Length /15: 304 Length /16: 6751 Length /17: 1003 Length /18: 2017 Length /19: 6275 Length /20: 4451 Length /21: 4316 Length /22: 6457 Length /23: 8429 Length /24: 58763 Length /25: 224 Length /26: 351 I was rather shocked by the number of /24's so I ran some further stats. Here is the top 25 offenders by origin AS: ASN: 701 routes: 1906 UUNet ASN: 1221 routes: 1775 ?????? ASN: 1 routes: 606 BBN Planet ASN: 2711 routes: 603 Rock Hill Telephone Company ASN: 7018 routes: 599 AT&T ASN: 7046 routes: 587 UUNet ASN: 1785 routes: 546 Applied Theory ASN: 705 routes: 537 UUNet ASN: 174 routes: 508 PSInet ASN: 8013 routes: 494 PSINet Canada ASN: 2551 routes: 463 ICG NetAhead ASN: 1239 routes: 453 Sprint ASN: 3561 routes: 365 Cable and Wireless ASN: 4293 routes: 355 Cable and Wireless ASN: 2548 routes: 346 Digex ASN: 2764 routes: 337 connect.com.au ASN: 3602 routes: 313 Sprint Canada ASN: 703 routes: 299 UUNet (Asia) ASN: 209 routes: 292 Qwest ASN: 2914 routes: 291 Verio ASN: 3301 routes: 271 RIPE ASN: 577 routes: 268 Bell Canada ASN: 3908 routes: 261 Supernet, Inc. ASN: 271 routes: 261 University of British Columbia ASN: 724 routes: 258 DLA Systems Automation Center Most of this waste seems to be coming from the Tier 2's, and for some reason a large number of people doing things like 100/24, 102/24, 104/24, etc, out of their larger netblocks. So here is a list considering the entire AS path (note I can't give an accurate number for gblx), which indicates those transiting the biggest offenders: ASN: 701 routes: 17867 UUNet ASN: 3967 routes: 8170 Exodus Communications ASN: 10910 routes: 5948 InterNap ASN: 1239 routes: 4967 Sprint ASN: 3561 routes: 3095 Cable and Wireless ASN: 209 routes: 3061 Qwest ASN: 6461 routes: 2383 AboveNet Communications ASN: 174 routes: 2347 PSInet ASN: 1221 routes: 2343 ??????

That block is listed as allocated by ARIN, but ARIN has nothing in the whois for them. I can produce a full list if anyone is interested.

Now I remember why I got out of the network security world, because its too darn depressing. A bunch of people meeting in the dark. http://www.nwfusion.com/news/2001/0205ddos.html I hear there are snowstorms on the east coast, that'll cheer me up.
