Please note this week's report is not accurate. This is due to an internal move of my workstation and consequently losing access to the router I use to get the information from. Normal service should resume in the next couple of days. Apologies for the inconvenience casued. --Tony Tony Bates <tbates@cisco.com> writes: * * This is an auto-generated mail on Fri Feb 13 12:00:00 PST 1998 * It is not checked before it leaves my workstation.

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 * * 2) Weekly Delta * * A summary of the last weeks changes in terms of withdrawn and * added routes.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. * * Check http://www.employees.org/~tbates/cidr-report.html for a daily * update of this report. * * *  * --------------------------------------------------------------------------- * --- * * CIDR REPORT for 13Feb98 * * * 0) General Status * * Table History * ------------- * * Date Prefixes * 290198 50396 * 300198 50242 * 310198 49848 * 010298 49715 * 020298 49739 * 030298 49600 * 040298 49877 * 050298 49484 * * Check http://www.employees.org/~tbates/cidr.plot.html for a plot * of the table history. * * * Possible Bogus Routes * --------------------- * * * AS Summary * ---------- * * Number of ASes in routing system: 2407 * * Number of ASes announcing only one prefix: 718 (0 cidr, 718 classfu * l) * * Largest number of cidr routes: 0 announced by * Largest number of classful routes: 1044 announced by AS701 * * *  * 1) Gains by aggregating at the origin AS level * * --- 13Feb98 --- * ASnum NetsNow NetsCIDR NetGain % Gain Description * * AS2493 691 368 323 46.7% iSTAR Internet, Inc. * AS6235 495 252 243 49.1% Intermedia Communications, Inc * . * AS4293 430 210 220 51.2% IMCI * AS174 874 673 201 23.0% Performance Systems Internatio * nal * AS816 635 444 191 30.1% UUNET Canada (ASN-UUNETCA-AS4) * AS3602 455 304 151 33.2% Sprint Canada Inc. * AS3749 202 61 141 69.8% TECNET * AS701 1044 931 113 10.8% Alternet * AS3336 109 19 90 82.6% Internet Services, Kolumbus pr * oje * AS3751 125 48 77 61.6% SNET-AS * AS5668 107 40 67 62.6% Century Telephone Inc. * AS3804 204 142 62 30.4% WORLDLINX * AS2048 154 92 62 40.3% LaNet * AS1239 596 534 62 10.4% SprintLink Backbone * AS3221 92 33 59 64.1% EENet Autonomous System * AS1 840 782 58 6.9% BBNPLANET * AS271 110 55 55 50.0% BCNET-AS * AS719 519 468 51 9.8% LANLINK autonomous system * AS549 214 163 51 23.8% ONET-AS * AS3464 115 64 51 44.3% Alabama Research and Education * Ne * AS1221 263 214 49 18.6% AARNET-AS * AS72 84 36 48 57.1% Schlumberger Information Netwo * rk * AS4763 128 80 48 37.5% Telstra New Zealand * AS7545 114 69 45 39.5% TPG Internet Pty Ltd * AS684 86 42 44 51.2% MBNET-AS * AS4740 354 312 42 11.9% ASN-OZEMAIL (Ozemail Pty Ltd) * AS2711 97 55 42 43.3% SUNBELT-AS * AS7046 130 89 41 31.5% UUNET-CUSTOMER * AS3561 897 857 40 4.5% MCI * AS852 156 117 39 25.0% CANET-ASN * * * For the rest of the previous weeks gain information please see * http://www.employees.org:80/~tbates/cidr-report.html *  * 2) Weekly Delta * * Please see * http://www.employees.org:80/~tbates/cidr-report.html * for this part of the report *  * 3) Interesting aggregates * * Please see * http://www.employees.org:80/~tbates/cidr-report.html * for this part of the report
