The easiest way to find the origin, without ending up having to comb your
hair with a towel, is to run a traceroute - the in-addr.arpa function of
the traceroute as it goes thru the various hops, should provide a domain
name at or very near that IP, such that it would give you someone to
complain to.

Failing that, or if you dont mind combing your hair with a towel, you can
see who owns that chucnk of address space, with rwhois, or maybe still
whois look ups, stepping up an octet as you go..
for instance

whois 100.1.1
if nothing
whois 100.1
if nothing
whois 100
if nothing, then give in and run a traceroute! :)
