On the 8 July update the following entry was added to the NSFNET policy routing database... 203.0/10 AUSTRALIA-CIDR-BLK C:AU 1:372 2:297 Expanded listing, sorted by country, then by organization: ========================================================== ... Australia --------- AARNet NIC, GPO Box 1142, Canberra, ACT, 2601, AUSTRALIA 1:372 Nasa Science Network (FIX-West) 2:297 Nasa Science Network (FIX-East) -------- 203.0/10 AUSTRALIA-CIDR-BLK (AU) On the 12th July I noted the following updates...

203.5.31/24 NET-TAU-AU C:AU 1:372 2:297 203.5.215/24 SILCARBURNIE-AU C:AU 1:372 2:297

203.6.125/24 AUS-GOV-DEF5-AU C:AU 1:372 2:297 203.6.126/24 AUS-GOV-DEF5-AU C:AU 1:372 2:297 203.6.127/24 AUS-GOV-DEF5-AU C:AU 1:372 2:297

It would appear to make some sense to remove all the specific announcements from the CIDR block 203.0/10 from the NSFNET PRDB, as long as NASA is announcing 203.0/10 to the NSFNET at FIX WEST, but as these come via NASA I was wondering what the story is. regards, Geoff Huston AARNet (in the interests of a smaller NSFNET routing table!)
