Why not list the netmask of the netblock as well?
In most cases you can figure out the netmasks. These blocks were only checked at the very beginning of their space based on the bgp announcement as viewed by our network. You can look at our AS1225 feed at route-views.oregon-ix.net
Checking only the beginning of nets for which you receive BGP announcements fails to take into account the vast numbers of single-homed networks which are part of large supernets. i.e. One of FDT's old UUNet IP blocks was a /20 in 205.228.0.0/14. There are only a few dozen announcements for: sh ip ro 205.228.0.0 255.252.0.0 longer ------------------------------------------------------------------ Jon Lewis <jlewis@fdt.net> | Spammers will be winnuked or Network Administrator | drawn and quartered...whichever Florida Digital Turnpike | is more convenient. ______http://inorganic5.fdt.net/~jlewis/pgp for PGP public key____
