There is no difference between static and dynamic address if it's on all the time. However, dynamic IPs for workstations make renumbering easier. You can't allow it for servers though. ___________________________________________________ Roeland M.J.

Or is ARIN going to say NO, you can't have 1000 addresses for your 1000 customers all of whom have their address "in use" 24x7 and force ISP's to use IP Masquerading at the ISP level to service all their dedicated customers. Heh. At that point, we'll just assign each ISP *ONE* IP address, and demand that they make it work beyond that point on their own. :) Should make routing tables significantly easier to manage. D

The Cidr Report
by Tony Bates 06 Nov '98

06 Nov '98

This is an auto-generated mail on Fri Nov 6 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

You know, I've got the same problem. I've been trying to think of a way to deal with one of my locations slower growth, yet higher profile customers. I want them to be able to route independantly should the links all go out between it and my other locales, but it doesn't grow fast enough to keep up with the others and I can't manage to get it into its own /19 without having to seal from its block as the time draws near to beg ARIN for more space. It might behoove ARIN to allow us /19s for locations like that on a special request form. -- Jason Weisberger Chief Technology Officer SoftAware, Inc. 310/305-0275

The trek across Canada
by jlixfeld＠industry.idirect.com 06 Nov '98

06 Nov '98

I'm looking for a cost-effective, highly reliable, high bandwidth, low latency solution for a link in Canada between Vancouver and Toronto. I have a couple of ideas: 1) Droping some type of high-speed interface into the frame-relay cloud of a third party network like AT&T, Sprint, MetroNet, or whoever provides this type of service. I think this would definetly be a scalable solution as it would allow us to put POPs anywhere we like in between and it would be as easy as running a circuit back into the frame cloud. The only issues with this is a) What are these networks like? Are they reliable? Are they fast? Is their a risk of them not being able to provide us with the bandwidth we paid for without performance loss due to lack of capacity (QoS)? 2) Assuming we buy our own fibre: Do we run a direct link between Toronto and Vancouver directly or drop a POP in between; somewhere in Saskatchewan or Manitoba and running fibre out of there to each? I may like the direct route from A to B but how pricy is that and how scalable is that? If we plan do put POPs into some some cities along the way we'd have to run pipes from those POPs back into either Toronto of Vancouver. If we go the route of A to B to C that would probably be a bit smarter as the haul from POP to POP wouldn't be so large. Is it common practice for the National ISP to lay their own pipe or is it more common practice to obtain the link from a third party? How do the UUNets, and BBNPlanets do it? They are not telcos so laying a pipe is not as easily justified. Do they buy fibre between A and B or do they even go through some sort of telco-like carrier?! If anyone has any ideas, opinions, experiences, or something to sell me I'd love to hear from you!

ARIN?
by alex＠nac.net 06 Nov '98

06 Nov '98

Again, we are applying for more space from ARIN. Some of the questions we got from them range from "please provide a network map and/or customers justification as to why they needed a /24" to "please provide where your POPs are, how many dialups there are in that POP, and how many ports you have in that dialup." I'd love to know if larger places (UU? PSI? MCI? Sprint? etc) have to answer questions like this when they apply for space. I don't want to hear an answer from ARIN, I would like feedback from actual customers of ARIN.
