This would have negated any issues that Princeton's networks were seeing. Properly configured, the only impact would've been that offending DHCP clients would not be able to use the network until they get a proper DHCP lease. There'd be no manual banning or need to contact your user. The user would probably contact you. All of the major networking hardware manufactures have some flavor of it: Cisco, HP, even Juniper claims to. I'd imagine the Princeton network uses something that would support this feature. *The particular related technology in Cisco world is "IP ARP Inspection".

Did you even rtfa? No one's name was taken. The only mention of that was by you in an attempt to relate to what you thought was going on in tfa you clearly didn't r. While that makes for nice fodder, it really adds nothing worthwhile.

Interesting story though. Maybe they really ARE out to get you.
