iplib scripts
-------------
ipconv.py
---------
This script show hot to use the IPv4Address class of the iplib module.
Given an IP address, show the IP in various notations.
Requires one argument: the IP address.
Options:
-i notation: force the input to be considered in the given notation,
otherwise it's autodetected.
-o notation: show the address only in the given notation.
Valid notations are: 'dot', 'hex', 'bin', 'oct', 'dec'.
nmconv.py
---------
This script show hot to use the convert_nm() function of the iplib module.
nmconv.py takes the same arguments and options of the ipconv.py script (additional
valid notations are: 'bits', 'wildcard').
cidrinfo.py
-----------
cidrinfo.py takes only one argument, a 'ip/netmask' CIDR notation, and
returns some informations about this subnet; e.g.:
$ cidrinfo.py 127.0.0.1/8
CIDR: 127.0.0.1/255.0.0.0
first usable IP address: 127.0.0.1
last usable IP address: 127.255.255.254
number of usable IP addresses: 16777214
network address: 127.0.0.0
broadcast address: 127.255.255.255
