Hi,

Hi,
I have this kind of shell script in order to set something on a bunch
of IP addresses:
for ACCEPTED_MACHINE in \
192.168.0.10 \
...
192.168.0.29
do
$IPTABLES [...]
done
How could I use a mask such as 192.168.0.0/NN to exactly match the list?
Thank you.
Use ipcalc!
The closest subnet is:
ipcalc 192.168.0.10/27
Address: 192.168.0.10 11000000.10101000.00000000.000 01010
Netmask: 255.255.255.224 = 27 11111111.11111111.11111111.111 00000
Wildcard: 0.0.0.31 00000000.00000000.00000000.000 11111
=>
Network: 192.168.0.0/27 11000000.10101000.00000000.000 00000
