Hi everyone,

FYI, as from tomorrow's posting, I've added more information to the daily 
report.

I list the size of the routing table after removal of all the subnets of 
announced prefixes - this isn't completely realistic as it takes no account 
of origin AS, but is an interesting number nonetheless. (Heading: Unique 
aggregates)

I also list the size of the routing table after per-AS aggregation is 
carried out. Some ASes deaggregate for traffic engineering purposes (those 
generally show a little de-aggregation) while others are doing it because 
of configuration errors or oversights. (Heading: Maximum Aggregation)

Tonight's run produced:

BGP routing table entries examined:                            107595
     Prefixes after maximum aggregation:                         71879
     Unique aggregates announced to Internet:                    51902

FYI2, I fixed a serious bug in counting the size of announced address 
space. I knew about it for a few months, but didn't have time to do the 
repair until this rainy weekend in Brisbane. This is why the amount of 
announced address space has dropped in the last few days.

Enjoy...!
