This is an auto-generated mail on Fri Mar 22 23:00:00 PST 2002 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. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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 GX Networks for giving me access to their routing tables once a day.

orbz screwup
by Ukyo Kuonji 22 Mar '02

22 Mar '02

A mail server I run a mailing list on has just been receiving refused messages, with the servers claiming that the server has been found to be an open relay by orbz. Upon investigating, I noticed that the orbz site is missing any information on sites on the list, and how to get sites off the list. This server is not an open relay. Even though I configured the server, I verified it after I received the message. Any ideas? _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

OT: Re: City apologizes for ORBZ shutdown....
by Joe Blanchard 22 Mar '02

22 Mar '02

Geez, And to think, all of those times I made a mistake I could have taken the person responsible for exposing it to court... Missed my chance. Guess an ACL for 216.120.158.120, 204.246.1.31 (and any other variants) is in order. Would hate for someone to accidentally bring down one of these systems due to a flaw on their end, and then get dragged in to a legal suit. LOL. Just my 2¢s Cheers -Joe Blanchard

Re: RE: long distance gigabit ethernet

Agreed, for the most part, especially when one is solely dependent on the incumbent carriers. I should point out, however, that some commercial enterprises are leasing their own lambdas from dark fiber providers who are running native GbE on their regional routes, both linear and ring-based, and those nets are becoming rather expansive. One such network that I am intimately familiar with now encompasses six northeastern states, and counting, adding segment after segment. Jitter on the larger ring circumferences? Yes, you betcha. Compensated for by either 3R regen or Layer 2 switching techniques or some other opaque- inducing means. When such routes are actually available and justifiable, the business problem then centers on risk assessment. I.e., will those fiber carriers continue to be viable for the foreseeable future? And so it goes...

Who offers it in the continental US? -I'm going to take a stab and assume that you're actually more interested -in finding a longhaul line with GigE on the ends, and not so much how many -miles you can get with whatever optics... Absolutely right, I don't care what's in between as long as I have GigE at the end. Other options include using wave (too expensive), or ethernet over MPLS (worth considering although latency may be too high for longer that 1000 miles). GP

Unwanted dial-outs
by Dave Garber 22 Mar '02

22 Mar '02

I have a question that I hope someone here can help me with. I have a client who is running a Windows 2k Advanced Server with 7 Windows 2k pro clients. They're setup with Sygate Office Network on the server for internet dial-out sharing. The problem we're having is unwanted calls made to the ISP (which is on a LD line... it's temporary until they move into their permanent office at which time they will be going with a broadband solution) randomly during the day by ALL of the 7 clients! The trigger event is to this domain - blackhole-1.iana.org. None of the clients are running any type of internet application when this occurs and I haven't been able to figure out what blackhole-1.iana.org is? What is triggering this event and why? Has anyone heard of this before? Any input is greatly appreciated! Dave Garber CompuHelp Unlimited/The Computer Cafe 724.776.5860
