Bgp: 63.0.0.0

Uunet has been announcing this for more than 2 days now. (not sure when
since I cleared my bgp tables 2 days ago).

Wow, I feel stupid now, they actually have a /9.

Ignore me :wink:

I was about to reply with that...Oh well, nobody is perfect!

Hmm.. I MIGHT be wrong here, but both:

63.0.0.0/10 and 63.64.0.0/10 are registered to UUNET (arin blocks:
NETBLK-NETBLK-UUNET97DU & NETBLK-UUNET63 )

These add up to 63.0.0.0/9, right? I mean, we DO want to aggregate this,
right?

I beg to differ...

c/o Tony Bates, UU are only kept off the top spot by Telstra's apparent policy
of deaggregating!

1) Gains by aggregating at the origin AS level

so I'm wrong and the two /10's can't be aggregated?
