Hi,
My binary skills are lacking, so does anyone know of a tool (online
or otherwise) to convert CDIR notation into the physical IP range? eg
convert 192.168.0.0/24 into 192.168.0.0 through 192.168.0.255 (so I
can see what the actual range is). TIA
Get the perl Net::CIDR module from CPAN.
I know I'm late, but did you try the dread "ipcalc" program that comes
with Linux?. E.g.
[root@prophead root]# ipcalc -n 192.168.0.71/26
NETWORK=192.168.0.64
That's your first address (the network)
[root@prophead root]# ipcalc -b 192.168.0.71/26
BROADCAST=192.168.0.127
And that's the last address (the broadcast). So, 192.168.0.71/26
covers 192.168.0.64 through 192.168.0.127, inclusive. Not too hard, eh?
"man ipcalc" for more details.
