  RFC 1918, previously RFC1597.

	  http://globecom.net/ietf/rfc/rfc1918.shtml
	
  or 
		
	  ftp://ftp.ds.internic.net:/rfc/rfc1918.txt

  Here is an excerpt from section 3:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)

] specifies the "reserverd networks" (i.e. the class A,B, & C [sic]
] network numbers that are considered "safe" (no-one should be routing them)
] to use as test/intranet/private IP networks?

] I need to know all of the numbers, i.e. I believe 10.0.0.0 is the class A
] component of the list.
