Subject: Telstra and global routing table bloat

AS1221 has been known for some time now to be sending out too many prefixes not based on CIDR boundries, thereby increasing the global router table size:

ASnum NetsNow NetsCIDR NetGain % Gain Description
AS1221 1652 1215 437 26.5% TELSTRA-AS

I hope Telstra can take the time to add the appropriate BGP filters so that the we all do not suffer from global router table bloat.

Seems some special odd transfer between ARIN and APNIC.
