Great tool, super useful.

Any chance ipv6 support would be added?

: netmask --version
netmask, version 2.4.4

: netmask asdf
netmask: parse error "
: echo $?
0

All errors have a zero return code. This makes it less then ideal for scripting.

thus

: netmask 192.168.1.255 && echo "valid address" 
  192.168.1.255/32
valid address

&

: netmask 192.168.1.256 && echo "valid address" 
netmask: parse error "192.168.1.256": Invalid argument
valid address

are both 'valid addresses'

netmask.c:310]: (style) Checking if unsigned variable 'v' is less than zero.
netmask.c:313]: (style) Checking if unsigned variable 'v' is less than zero.

Source code is

      if(v < 0 || v > 32) return 0;

and

     if(v < 0 || v > 128) return 0;

Hi,
I just came across this useful tool via serverfault.

I wanted to generate cidr for everything in the 10.0.0.0/8 except for 10.7.0.0/16.
The following worked well enough:

$ netmask -c 10.0.0.0:10.6.255.255  10.8.0.0:10.255.255.255
   10.0.0.0/14
   10.4.0.0/15
   10.6.0.0/16
   10.8.0.0/13
  10.16.0.0/12
  10.32.0.0/11
  10.64.0.0/10
 10.128.0.0/9

However, I wonder would you consider something like:

 $ netmask -c 10.0.0.0/8 --exclude 10.7.0.0/16

Thanks for the good work.

README says... "See the file INSTALL for building and installation instructions."
Seems to be missing.

Update: The following works to compile on Ubuntu 20.04...
./autogen
./configure
sudo apt-get install texinfo # I was missing makeinfo
make
