Confronting Address Space Hijackers

Tawn writes "There's a great story on SecurityFocus about hijackers taking over large allocations of IPv4 space with forged documents and false business fronts. Los Angeles County and some big multinationals have had /16's pulled out from under them in the last few months, and used to inject spam. ARIN and network operators are trying to get a handle on the problem. The owner of a webhosting company that wound up with L.A. County's /16 called it 'borrowed space,' and said he paid $500 for it to a guy he met online."
