IP Addressing

AutoNetkit.algorithms.ip.get_ip_as_allocs(network)

Returns list of Subnets allocated, by network

AutoNetkit.algorithms.ip.allocate_subnets(network, address_block=IPNetwork('10.0.0.0/8'))

Allocates subnets and IP addresses to links in the network.

Args:

address_block (IPNetwork): The address block to use.

Returns:
