I think it would be wise to block the offending IPs for some time(using
.htaccess). If they similar, then block their entire C class block. I 
had an
attack of this kind sometime back & blocked 2-3 C class blocks that were
the repeat offenders for sometime. this might loose out on some
legitimate traffic but its worth it in my opinion.

also, if your host is not an idiot, they wouldn't label you as a trouble 
if you go to them with this problem. it would be wise as well to let 
know of the problem, as they are better equipped to handle the situation
than you are, as they too don't want someone sniping away at their
server, possibly a DoS attack!! :)
