Hi I saw rfc1918 list only the private addresses
( as its title suggests )
<RFC1918>
3. Private Address Space
The Internet Assigned Numbers Authority (IANA) has reserved the
following three blocks of the IP address space for private internets:
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)
</RFC1918>
but in most of the solutions to deny rfc 1918 address I see lot more
addresses in the deny ace s ??
access-list 111 deny ip host 0.0.0.0 any
access-list 111 deny ip 1.0.0.0 0.255.255.255 any
access-list 111 deny ip 2.0.0.0 0.255.255.255 any
access-list 111 deny ip 5.0.0.0 0.255.255.255 any
access-list 111 deny ip 7.0.0.0 0.255.255.255 any
access-list 111 deny ip 127.0.0.0 0.255.255.255 any
access-list 111 deny ip 224.0.0.0 31.255.255.255 any
access-list 111 deny ip 10.0.0.0 0.255.255.255 any
access-list 111 deny ip 172.16.0.0 0.15.255.255 any
access-list 111 deny ip 192.168.0.0 0.0.255.255 any
Is this not including part of RFC3330 / &| / IANA reserved addresses as well
?
Thanks
Kal
