I wish this was all so simple. Inclusion of tagging Internet traffic is still in the IETF process AFAIK. As I recall from a CP talk given in 2000 by Hugh Daniel, the proposals would have routers connecting an entry-point (e.g., a user at an ISPs) send a relatively small number of out-of-band messages, related to packets randomly chosen from its queue, to the end-point router (as noted in the packet headers). These messages would contain the "true" source and destination addresses as known to the sending router. For those packets which the end-point router received such a message it could immediately identify address spoofing and other nasties.Markoff writes in the NY Times about a proposal called eDNA which would "reconfigure" the Internet to forbid anonymous usage of certain parts.http://www.nytimes.com/2002/11/22/politics/22TRAC.html The scheme was explored by DARPA a few months ago, which gave a contract to SRI to look into it. SRI convened a panel that included Matt Blaze, Whit Diffie, Roger Needham and Marc Rotenberg (of EPIC). These guys hated the idea, but the SRI contact, one Victoria Stavridou, refused to allow Blaze to write up the consensus once it became clear that he was going to shred the proposal.
