RIPE NCC region routing summary
by Philip Smith 09 Apr '00

09 Apr '00

Hi, As I discussed at the IEPG in Adelaide Australia, I have been posting weekly stats about the state of the Asia Pacific routing table to the AP Operators mailing list (apops(a)lists.apnic.net) Basically I am examining the view of the Internet routing table as obtained from NSPIXP2 in Tokyo, mostly for the benefit of the region's ISPs. At the same time I have been producing statistics for the region covered by the RIPE NCC (and for the region covered by ARIN). Would it be interesting if I posted the European summary to this list? It is no more intrusive than the CIDR Report which Tony Bates posts on a weekly basis, and gives what I believe is a view which is more focused on the region covered by the RIPE NCC. I've included a sample output at the end of this e-mail, fyi. More information is displayed in graphical form on the APNIC web page, specifically: http://www.apnic.net/stats/bgp best wishes! philip -- Europe, Middle East, North Africa Report 31 Mar, 2000 Analysis Summary ---------------- BGP routing table entries examined: 76791 Origin ASes present in the Internet Routing Table: 7095 Origin ASes announcing only one prefix: 2267 Transit ASes present in the Internet Routing Table: 1018 Average AS path length visible in the Internet Routing Table: 5.2 Max AS path length visible: 14 Illegal AS announcements present in the Routing Table: 1 Non-routable prefixes present in the Routing Table: 0 Prefixes being announced from the IANA Reserved Address blocks: 5 Number of addresses announced to Internet: 1137130310 Equivalent to 67 /8s, 199 /16s and 59 /24s Percentage of available address space announced: 30.7 Percentage of allocated address space announced: 61.8 Percentage of available address space allocated: 49.6 RIPE Region Analysis Summary ---------------------------- Prefixes being announced by RIPE Region ASes: 12413 Prefixes being announced from the RIPE address blocks: 9649 RIPE Region origin ASes present in the Internet Routing Table: 1918 RIPE Region origin ASes announcing only one prefix: 890 RIPE Region transit ASes present in the Internet Routing Table: 372 Average RIPE Region AS path length visible: 5.8 Max RIPE Region AS path length visible: 14 Number of RIPE addresses announced to Internet: 67254447 Equivalent to 4 /8s, 2 /16s and 56 /24s Percentage of available RIPE address space announced: 66.8 RIPE AS Blocks 1877 - 1901, 2042, 2047, 2107 - 2136, 2585 - 2614 2773 - 2822, 2830 - 2879, 3154 - 3353, 5377 - 5631 6656 - 6911, 8192 - 9215, 12288 - 13311, 15360 - 16383 RIPE Address Blocks 62/8, 193/8, 194/7 and 212/7 RIPE Region per AS prefix count summary --------------------------------------- ASN No of nets /19 equiv Description 3301 439 283 TeliaNet Sweden 1257 351 250 Swipnet AB 1270 249 410 UUNET Germany 1275 234 1148 DFN IP Service 1849 214 452 PIPEX 719 180 145 LANLINK 786 179 943 JANET IP Service 517 167 197 Xlink 5515 153 318 Sonera Finland 3320 131 233 Deutsche Telekom AG 3303 124 319 Swisscom 2609 123 4 EUnet-TN 2856 122 271 BTnet UK Regional network 3215 100 118 RAIN 1901 87 74 EUnet Austria 2874 87 84 Global One Services 1290 84 195 PSINet UK Ltd. 8895 83 28 Saudi Arabia AS 3269 82 182 TELECOM ITALIA Global Per AS prefix count summary ---------------------------------- ASN No of nets /19 equiv Description 701 2016 3442 UUNET Technologies, Inc. 7018 990 3053 AT&T 1221 953 1120 Telstra 1 831 4583 BBN Planet 3561 823 1692 Cable & Wireless USA 1239 720 1630 Sprint ICM-Inria 2914 719 1173 Verio, Inc. 209 673 706 Qwest 7046 673 421 UUNET Technologies, Inc. 174 639 2845 PSINet Inc. 271 472 411 BCnet Backbone 2764 439 120 connect.com.au pty ltd 3301 439 283 TeliaNet Sweden 3602 424 77 Sprint Canada 3549 415 318 Frontier GlobalCenter 705 414 23 UUNET Technologies, Inc. 1785 410 872 Sprint ICM 816 398 179 UUNET Canada4 4740 394 82 Ozemail List of Illegal AS's (Global) ----------------------------- Bad AS Designation Network Transit AS Description 65502 PRIVATE 159.98.0.0/17 3369 MCI Advertised IANA Reserved Addresses ---------------------------------- Network Origin AS Description 1.1.1.0/24 209 Qwest 65.45.0.0/19 10585 NETLIMITED LLC 197.138.137.0/24 2914 Verio, Inc. 219.91.160.0/22 7742 InternetNow, Inc. 219.91.164.0/23 7742 InternetNow, Inc.

The Cidr Report
by Tony Bates 31 Mar '00

This is an auto-generated mail on Fri Mar 31 12:00:00 PST 2000 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
