I used the list posted at iana and created the list in the what I think is better for use by own whois server. Its likely to be of use to others.

The list is available at http://www.completewhois.com/iana-ipv4-addresses I'm also posting it here below (you're free to modify or not and use it for whatever purposes you desire): Address Globally Last Change RIR whois Responsibe RIR Comments Block Routable Date server for allocation (Purpose) ------- --------- ---------- -------------- ---------------- ----------------------- 000/8 N Sep-81 none IANA IANA - Reserved 001/8 N Sep-81 none IANA IANA - Reserved 002/8 N Sep-81 none IANA IANA - Reserved 003/8 Y May-94 whois.arin.net IANA General Electric Company 004/8 Y Dec-92 whois.arin.net IANA Genuity/BBN (IANA INFO: Bolt Beranek and Newman Inc.) 005/8 N Jul-95 none IANA IANA - Reserved 006/8 Y Feb-94 whois.arin.net US-DOD Army Information Systems Center 007/8 N Apr-95 none IANA IANA - Reserved 008/8 Y Aug-92 whois.arin.net IANA Genuity/BBN (IANA INFO: Bolt Beranek and Newman Inc.) 009/8 Y Aug-92 whois.arin.net IANA IBM 010/8 N Jun-95 none-rfc1918 IANA IANA - Private Use.
