[nsp-sec] hijacked netspace

[Dario Ciccarone (dciccaro)]

Interesting. Which methods to Transworld use ? :)

I know it's starting to look like "newbie" day - a URL or pointer to a
document (if such a document exist - previous NANOG meetings?)
explaining methods Transworld/other ISPs use besides blackholing would
be much appreciated.
