fuzzfuzzfuzz! :)

btw, to respond to one of your comments that i noticed after a quick glance 
through the dhcp fuzzer-- RFC951 (BOOTP, precursor to DHCP) states "For 
simplicity it is assumed that the BOOTP packet is never fragmented". i can't 
see mention of fragmentation in RFC2131 (DHCP itself), though there is an 
internet draft i found that seeks to define an application layer fragmentation 
process for DHCP. 

it doesn't appear to be actually forbidden though -- given that DHCP is in the 
process of configuring the stack anyway, i could well imagine this is a corner 
case that isn't particularly well defined or consistently (or well) handled...
