Hi Leo,

How do you figure that "more ARIN qualifying orgs = increased routing
table" is a reasonable assumption?

Let me rephrase the question by expanding your assumption a little bit:

1. Multivendor multihomed user connects to the Internet.
2. User announces his ISP /24 via BGP.
3. User qualifies for an ARIN /24
4. ...
5. ...
6. User announces more than just one /24.

What are steps 4 and 5 that get you from qualifying for an ARIN /24 to
consuming extra BGP slots?
