My theory - not yet backed by data - is that probably most spoofed traffic these days does in fact emanate from IDC networks, and that a non-trivial proportion of same emanates from a relatively small number of such networks. In many cases, it's possible to put 'naked' hosts on home broadband connections, however - and how common that is, and what proportion of those broadband access networks don't run any form of anti-spoofing, is an open question. ----------------------------------------------------------------------- Roland Dobbins <[email protected]> // <http://www.arbornetworks.com> Luck is the residue of opportunity and design. -- John Milton
