I've noticed that ARIN is the only one of the RIRs that has a whois server that doesn't accept CIDR style queries. For example:
: dlw@corp:575 ; whois -h whois.apnic.net 10.0.0.0/8
% [whois.apnic.net node-1]
% Whois data copyright terms http://www.apnic.net/db/dbcopyright.html
inetnum: 10.0.0.0 - 10.255.255.255
: dlw@corp:576 ; whois -h whois.arin.net 10.0.0.0/8
CIDR queries are not accepted
No match found for 10.0.0.0/8.
CIDR queries really should work. Thanks!

ARIN will add the request to the list of considered future enhancements for WHOIS.
