I was wondering why a non-allocated AS was being allowed to announce the blocks but it appears that APNIC has revoked the 63854 ASN? http://wq.apnic.net/apnic-bin/whois.pl?searchtext=AS63854&object_type=aut-num Based on google's cache, it was still there late March. BGP routing table entry for 103.41.125.0/24, version 108425142 Paths: (1 available, best #1, table default) Not advertised to any peer 6939 4134 36678 26484 63854 Blake Hudson wrote:
Reading the article, I assumed that perhaps Level 3 was an upstream carrier, but RIPE stats shows that the covering prefix (103.41.120.0/22) is announced by AS63509, an Indonesian organization. It looks like they're fighting back by announcing their own /24 now. I love the AS's address: descr:Jl. Marcedes Bens No.258 descr:Gunung Putri, Bogor descr:Jawa Barat 16964 country:ID While a Level 3 /24 announcement will certainly have a world wide impact, I agree that it seems misguided when the originating AS can announce their own /24. It does make one wonder why Cisco or Level 3 is involved, why they feel they have the authority to hijack someone else's IP space, and why they didn't go through law enforcement. This is especially true for the second netblock (43.255.190.0/23), announced by a US company (AS26484). --Blake
