Weren't they changed to decrement once, appearing as one instead of two routers? (For those who don't remember the NSFNET "routers" they consisted of an IBM RS6000 attached to each of several T1/T3 interfaces, interconnected across a FDDI with a route server. Nine RS6000s in all. 200 amp service required. :-) This is no reason to raise a harmful alarm. --Kent

The easiest thing in the world; already proposed weeks ago (now months ago) for WhoIs in general [using the specified problem as example]: 1. Users spot errors (Dal saw that the IPs for youwant.to were wrong). 2. Users send an email to InterNIC regarding errors, including methodology and other resources used to discover that the info was erroneous. 3. InterNIC verifies information provided in email (look at WhoIs, verify that the methodology was sound, etc.) 4. If the information is clearly a lie (such as a phone number of 555-1212), InterNIC deletes the domain (as provided in para L of the Registration Agreement). If the information might be an error (transposed numbers in IP), InterNIC sends an email (again, as provided in the Registration Agreement) requesting clarification. 4a. If the domain does not reply with the 30 days mentioned in the Registration Agreement, or if the email bounces, the domain is deleted. 5. Problem solved, database corrected, slimeball taken down. 5a. In the event of an erroneous deletion, the domain is simply reinstated. 5b. If the slimeball liar wants to re-register, he/she/it pays another $100. A simple, cost-effective solution to the problem. No new hardware needed. No new software needed. POSSIBLY a single employee needed (although since the problem is self-diminishing, using an existing employee would probably work fine). According to the July 97 IPO filing with the SEC, NSI earned a net profit of $391,688 Jan-Mar 97 from domain registrations, so there's no cost barrier to the solution. Now...why can't this be done?

The Cidr Report
by Tony Bates 20 Mar '98

20 Mar '98

This is an auto-generated mail on Fri Mar 20 12:00:00 PST 1998 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.

Alex, Did you mean Detroit Metro airport or Detroit City Airport? Metro Airport should be your first choice. It is within 10 minutes driving time. City airport is much a smaller airport a bit further away. Still not too far away via I-94. *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* | Harold Willison AGIS Network Engineering | * Network Engineer 313-730-5151 * | News Admin. 313-730-1130 | | news(a)agis.net 24 hours a day, 7 days a week | * harold(a)agis.net noc(a)agis.net * | <bold><italic> <underline>http://www.agis.net</underline></italic></bold> |<bold><italic> </italic></bold>\*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*/

> I consider Windows 95 to be the least common denominator, > which has a default IP TTL of 32. Yes, 32. So that implies > that each NSP should decrement no less than 8 TTLs. That's broken. I quote from RFC 1340, dated July 1992: The current recommended default time to live (TTL) for the Internet Protocol (IP) [45,105] is 64. This does not change reality, of course, but it also does not make it less broken. - Håvard
