Subnetting in Python with IPv6
We can also find the subnet information from the IPv6Network objects, as follows:
>>> subnets = list(net6.subnets()) >>> subnets [IPv6Network('2001:db8::/49'), IPv6Network('2001:db8:0:8000::/49')]
The ipaddress module includes various functions to create subnets and supernets, so we can check whether a network overlaps:
>>> ipnet = ipaddress.IPv6Network("2001:db8::/48") >>> list(ipnet.subnets()) [IPv6Network('2001:db8::/49'), IPv6Network('2001:db8:0:8000::/49')]
We can use the subnets method to expand the network mask and obtain new networks:
>>> list(ipnet.subnets(prefixlen_diff=4)) [IPv6Network('2001:db8::/52'), IPv6Network('2001:db8:0:1000::/52'), IPv6Network('2001:db8:0:2000::/52'), IPv6Network('2001:db8:0:3000::/52'), ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
