Updated patch, also optimizing v6 netmask parsing (same principle). Before patch: $ ./python -m timeit -s "import ipaddress" "net = ipaddress.IPv6Network(('2001:db8::', 96))" 10000 loops, best of 3: 26.1 usec per loop $ ./python -m timeit -s "import ipaddress" "net = ipaddress.IPv4Network(('10.0.0.0', 23))" 100000 loops, best of 3: 17 usec per loop After patch: $ ./python -m timeit -s "import ipaddress" "net = ipaddress.IPv6Network(('2001:db8::', 96))" 100000 loops, best of 3: 13.8 usec per loop $ ./python -m timeit -s "import ipaddress" "net = ipaddress.IPv4Network(('10.0.0.0', 23))" 100000 loops, best of 3: 14.3 usec per loop
