If I understand the thread correctly, part of the growth problem in the routing tables has been attributed to small clients with sub/24 address allocations implementing multi-homed solutions. As an Internet Access Provider (IAP), I thought I'd share a few opinions... + ip allocation + Address allocation is not very pretty when you start to move down from the tier 1's. Upstream providers tend to grab the "next available" /22, /23, or /24, which is usually located about a thousand miles away from your current allocation. (Well, you should have planned for growth...) Agreed, but ARIN and most upstreams do not accept "I think I'm gonna quadruple my customer base next year" as a viable excuse. And for good reason, given the allocation abuses that have occured in the past. So now we have these IAP's with multiple /24's scattered haphazardly across the upstream provider's delegated block. Now what happens when this IAP multi-homes? (There are very few valid reasons to multi-home, please consult with RFC x, BCP y, and an experienced network engineer.)
