i noticed some pretty poor aggregation in some of the most recently allocated address space tonight: (advertising as's withheld to protect the innocent/guilty)
208.201.64.0/21 208.201.73.0 208.201.88.0/21 208.201.97.0 208.201.103.0 208.201.112.0/22 208.218.64.0/20 210.135.160.0/20 210.135.192.0/22 210.135.224.0/20
this seems especially bad with all the talk of better ways to allocate and advertise so that we don't waste address space. i do note that most of what i call poor aggregation appears to be due to "dual homing". are we just doomed to poor aggregation because of this?
or maybe i'm just naive in thinking the internic is really cracking down on small allocations and that providers are really working hard to aggregate.

Hmm. Maybe a neutral, 3rd-party agency to get dumps of tables from major entities and which would send e-mail with suggested aggregations to noc@theownerofeachoffendingasn. I will make time to start running the route aggregator at routes.netaxs.com again; we've been fighting a random-src-address-SYN-attacker for the last week or two. I may have some comments on THAT for NANOG re: inter-provider cooperation shortly. Avi
