CIDR Brewer

CIDR Brewer is a command-line utility which displays information for
classless IP addresses (such as subnet mask and network ID) so you don't
need to perform the calculations yourself.
Installing
----------
You can install CIDR Brewer via pip (ideally globally):
::
pip install cidr-brewer
Usage
-----
To use, run ``cidr-brewer`` from the command line with one or two IP
addresses.
One IP address
~~~~~~~~~~~~~~
If you pass a single IP address using slash notation, CIDR Brewer will
compute the subnet mask, network ID, broadcast ID, and the range of
valid/available IP addresses.
::
$ ./cidrbrewer.py 192.168.19.100/25
Given IP address:
192.168.19.100/25 11000000.10101000.00010011.01100100
Subnet mask:
255.255.255.128 11111111.11111111.11111111.10000000
Network ID:
192.168.19.0/25 11000000.10101000.00010011.00000000
Broadcast ID:
192.168.19.127 11000000.10101000.00010011.01111111
First Available Address:
192.168.19.1 11000000.10101000.00010011.00000001
Last Available Address:
192.168.19.126 11000000.10101000.00010011.01111110
Subnet Size: 2^7 - 2 = 126
Additionally, if you supply a list of block sizes, CIDR Brewer will
compute the same information for each sub-block.
::
$ ./cidrbrewer.py 42.114.152.128/25 --block-sizes 16 64 16 32

Two IP addresses
~~~~~~~~~~~~~~~~
If you pass two IP addresses (without slash notation), CIDR Brewer will
also compute the largest subnet mask needed for communication between
the two addresses.
::
$ ./cidrbrewer.py 172.16.11.74 172.16.11.78
Given IP addresses:
172.16.11.74 10101100.00010000.00001011.01001010
172.16.11.78 10101100.00010000.00001011.01001110
Largest subnet mask allowing communication:
29 bits
255.255.255.248 11111111.11111111.11111111.11111000
Network ID:
172.16.11.72/29 10101100.00010000.00001011.01001000
Broadcast ID:
172.16.11.79 10101100.00010000.00001011.01001111
First Available Address:
172.16.11.73 10101100.00010000.00001011.01001001
Last Available Address:
172.16.11.78 10101100.00010000.00001011.01001110
Subnet Size: 2^3 - 2 = 6
If you pass two IP addresses (with slash notation), CIDR Brewer will
also indicate if the IP addresses can already communicate on their
respective subnets.
::
$ ./cidrbrewer.py 125.47.32.170/25 125.47.32.53/25
Given IP addresses:
125.47.32.170/25 01111101.00101111.00100000.10101010
125.47.32.53/25 01111101.00101111.00100000.00110101
Can these IP addresses communicate?
No
Largest subnet mask allowing communication:
24 bits
255.255.255.0 11111111.11111111.11111111.00000000
Network ID:
125.47.32.0/24 01111101.00101111.00100000.00000000

Last Available Address:
125.47.32.254 01111101.00101111.00100000.11111110
Subnet Size: 2^8 - 2 = 254
