Re: Internic address allocation policy

I know of one large ($1 Billion+) retailer who was assigned 5 Class C's two months ago by MCI for a DMZ network, one for each division sharing the link. 1270 addresses is a hell of a lot of proxies and email gateways...

"Still, MCI's Gross noted that one unidentified member of the engineering task force recently condemned RSVP as, according to Gross, "the biggest fraud ever perpetrated on the Internet community."" (nov 18, page 16) Does anybody know who that "unidentified member" is? I would like to buy him beer. --vadim

Sprint install folks have this tendancy to put in static routes regardless of whether you're peering or not. At least that's been my experience getting multi-line setups installed. I'm only half-kidding when I suggest telling a sprint installer "yeah we have our own IPs, 172.16/16". If you do end up peering then they seem to put a static in for the class C that contains your loopback interface. You can get them to change it, but the default seems to be static-everything. Do any providers reserve ips for use on loopbacks? i.e. nets they divide into /32s to point at loopbacks on the customer router. This would seem to be a prudent measure for many multihomed customers -- I'm loathe to use any PI addresses for loopback-peering because of the potential for mistakes with static routes to the loopback address.

I'm suggesting that perhaps we should consider the set of all routers since we're concerned about spreading load due to the quick communication from one router to many of every best external-path changing. But no, I'm not familiar with SS7, and I've not even been thinking deeply about other routing algorithm possibilities. I was just suggesting that people are encouraged to do so... Avi

I thought this meeting announcement may be of interest to members of this list (especially if you are in the mid-atlantic) Russ Haynal The Washington DC Chapter of the Internet Society (DC-ISOC) announces its Next Event! Domain Names - Issues, Policies, and Solutions Tuesday, December 3, 1996, 7-9 p.m. There have been many pressures building on the Domain Name System, including rapid growth of .com, trademark disputes, and increasing amounts of litigation. Join DC-ISOC to hear from Industry leaders how domain names are being handled and what steps are being taken to possibly expand the domain name space. Confirmed speakers include: Dr. Donald N. Telage, President and COO of Network Solutions, Inc., which manages the InterNIC Registry administering the .com, .net, .edu, and .org top level domains. Dr. Telage will discuss: - Issues involved in operating a domain name registry. - The latest Internic policies for handling domain name disputes - Network Solution's initiatives to ensure that Internic operations keep pace with the rapidly evolving Internet Donald M. Heath, President and CEO of the Internet Society. Don also serves as chairman of the Internet International Ad Hoc Committee (IAHC) which is charged with looking at the complex issues surrounding the current domain name and registry situation, including trademark and infringement, economics and administration of registry operations, dispute policies, fees and international Top Level Domain (iTLDs). The meeting will be held on Tuesday, December 3, 1996, at the Marriott Hotel in Tysons Corner from 7-9 p.m. Please arrive prior to the meeting start time of 7pm. Directions: Washington Beltway (I-495) Exit for Route 7 (Leesburg Pike) heading west. The Marriot is located immediately on your right.

The Cidr Report
by Tony Bates 17 Nov '96

17 Nov '96

This is an auto-generated mail on Fri Nov 15 12:00:00 PST 1996 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. In the future I hope to put some (or most) of this report up on the web. ------------------------------------------------------------------------------ CIDR REPORT for 15Nov96 0) General Status Table History ------------- Date Prefixes 091196 42664 101196 42653 111196 42696 121196 42728 131196 43235 141196 42370 151196 42021 Possible Bogus Routes --------------------- AS Summary ---------- Number of ASes in routing system: 1792 Number of ASes announcing only one prefix: 737 (378 cidr, 359 classful) Largest number of cidr routes: 461 announced by AS3561 Largest number of classful routes: 1266 announced by AS174 1) Gains by aggregating at the origin AS level --- 15Nov96 --- ASnum NetsNow NetsCIDR NetGain % Gain Description AS174 1266 925 341 26.9% Performance Systems International AS1 837 511 326 38.9% BBN Planet backbone AS3602 652 344 308 47.2% Intergrated Network Services Inc.

Mapping IP -> ASN
by Lyndon Nerenberg 16 Nov '96

16 Nov '96

Is there a tool available that will take an IP address and return the ASN attached to that network? I've been in situations before where this information would be useful, but not having access to the BGP routing information I'm not sure how to do this? (I've looked around some "likely" web sites - such as Merit - but haven't found anything.) The pressing need is for the ASN associated with 198.161.92.0. This network is connected to I*star, but I can't tell which of I*star's three ASNs it's homed on. (And they aren't being responsive to queries.) --lyndon
