Did anyone hear about or see problems on Sprint Internet this past weekend (11/7 &11/8)? If so, where can I find some detailed info on the problems (cause, solution, etc.)?

I know a little bit about @Home, but not as much as the people who work there, so feel free to yell & scream if I mess this up. I do believe you are correct in your implication that @Home does not utilize address space quite as efficiently as most traditional ISPs. However, they are under a greater burden than your traditional ISP. Most of the equipment they were forced to use in the "early days", and possibly a good deal of it today, is not what I would call "optimal". They are forced to allocate /24s to some cable routers no matter how few customers there are on that router. Most do not understand classless IP, or even basic subnetting. Etc., etc. The point is, the people I know at @Home do try very hard to use their IP space within reason. But there are some things they just can not do. There are two sides to every story.

[Someone with a clue one said...*grin*] Hrmmmm, you have a major point. Suppose only routers costing 6 figures or more could do CIDR, while routers costing, say, four figures could do RIPv1? Should we give someone a large block to get "up and running" until they could afford the much more expensive routers? (stuff deleted) See, I just don't think "Address Space" should be a barrier to entry. It's not like ARIN *owns* the space, they're just the caretaker for the IPv4 space in America for the "community". As a member of the community, I want them to be fugal to avoid waste. But unusually large (and temporary) allocations to allow a company to enter the market - a company that would otherwise have to perform Herculean tasks, tasks none of the rest of us have ever had to perform, or maybe even tasks impossible with the State of the Art - is not, IMHO, waste. --- What about the case of an NSP looking to obtain a block to begin business with? A case where the parent company (via direct ownership and mergers) holds a couple of /16 allocations across a nationwide LAN infrastructure, and at the same time is not able to deliver to a spinoff arm of the company a 'clean' chunk of space to bring up a very large Internet Backbone. At the same time, the parent company has 0 SWIP documentation of the existing /16s and is still about 18 months away from a total migration to 10.x.x.x space internally. What is ARINs job at this point? To force the spinoff to document the IP allocations within the Sister company before they allow you to do business, or based on the current and future deployment (and CIDR capabilities) allocate sufficient address space to allow the business to launch and grow.

Another note on this, I wasn't able to stop the updates with a filter-list... perhaps because the AS path is problematic.

I don't believe that a ceiling on number of posts is a solution at all. When an issue occurs that requires, or at least RATES discussion, it would stifle effective communication. I disagree with taking all issues offline to private email as well. While I can see where it would dramatically decrease the number of messages on the list of we did so and then submitted one email with "notes" of the discussion, it will also stifle communication. Not everyone is going to pipe when they see the first or even third email on a subject. Suggestions and opinions often require some thought after reading through the thread and though some might think of the thread as idle chatter over some issue they have no interest in, others find it interesting and even educational. >At 11:57 PM 11/2/98 -0700, Forrest W.

IRR/RADB updates vs. ANS?
by Daniel Senie 08 Nov '98

08 Nov '98

I'm looking for information on how and/or when ANS takes updated information from the IRR databases (RADB in this case) and applies them internally. I've got a case where a net has just been moved from one ISP to another, and while a new entry was placed in the RADB, there is no connectivity from the net in question to anyplace in ANS. >From various observations, ANS is the only net not accepting routes for this particular net. I've looked at the various looking glass servers, and of the ones I know of, everything looks OK (and indeed connectivity is OK). Are there any looking glass capabilities to see what ANS is routing? One guess is that ANS only takes new data from the RADB on a set schedule and insufficient time has elapsed for that data to reach their internal files. I've got a number of other nets to be moved shortly, so I'd really like to be clear on how this works. It appears that very few nets rely on the data in the RADB, or take updated data from the RADB in near-real-time fashion. Any/all info appreciated.
