Only 1 question:
What about the companies that have a /24 out of the /20 0r /21 that are multi-homed?
If the route rules are not carefully prepared the multi-homed customer then might be single-homed and tied to the upstream they got the IP's from.

Thoughts?
I was curious how much of the de-aggregation was due to multi-homed companies requiring the longer prefixes. Are there companies that actually announce their smaller routes despite controlling the shorter prefix? What would be the benefit of doing so?
