prettyip 1.1.3

Compatibility

Everywhere IPy runs, so does this – CPython-2.6 through 3.4.

Usage

Explicitly:

from IPy import IPSet, IP
import prettyip

my_ipset = IPSet([IP('10.0.0.0/8')]) - IPSet([IP('10.0.1.2')])
print prettyip.pretty_ipset(my_ipset)

Or, monkey-patch IPy:

import prettyip

prettyip.patch_ipy()

my_ipset = IPSet([IP('10.0.0.0/8')]) - IPSet([IP('10.0.1.2')])
print my_ipset

Results

Simple IPs:

 >>> prettyip.pretty_ipset(IPSet([IP('10.0.0.0/8')]))
'10.0.0.0/8'

Ranges:

>>> IPSet([IP('10.120.13.11'), IP('10.120.13.12/30'), IP('10.120.13.16')])
IPSet([IP('10.120.13.11'), IP('10.120.13.12/30'), IP('10.120.13.16')])
>>> prettyip.pretty_ipset(_)
'10.120.13.1{1-6}'

Big netblocks with smaller pieces missing:

 >>> IPSet([IP('1.0.0.0/8')]) - IPSet([IP('1.0.1.0/24')]) - IPSet([IP('1.0.9.0/24')])
 IPSet([IP('1.0.0.0/24'), IP('1.0.2.0/23'), IP('1.0.4.0/22'),
    IP('1.0.8.0/24'), IP('1.0.10.0/23'), IP('1.0.12.0/22'), IP('1.0.16.0/20'),
    IP('1.0.32.0/19'), IP('1.0.64.0/18'), IP('1.0.128.0/17'),
    IP('1.1.0.0/16'), IP('1.2.0.0/15'), IP('1.4.0.0/14'), IP('1.8.0.0/13'),
    IP('1.16.0.0/12'), IP('1.32.0.0/11'), IP('1.64.0.0/10'),
    IP('1.128.0.0/9')])
 >>> prettyip.pretty_ipset(_)
'1.0.0.0/8 except 1.0.1.0/24, 1.0.9.0/24'
