an effect of ignoring BCP38

[bmanning () vacation karoshi com]

seems that some folks in the R&E community, with institutional support
from Cisco, Google, and the US NSF, are exploiting our inability to
take even rudimentary steps toward providing a level of integrity in
routing by teaching students that spoofing IP space is ok.  This whole
thing works at all because so few people use/deploy/maintain BCP-38
compliance.  This was an eye-opener for me.
