View Source

finds an ip address and subnet together from a config representation (this is an ip/cidr string where the ip is not necessarily the routing prefix for the cidr block).

This function is useful if you have configuration files that specify IP address/subnet identities in this fashion (for example ifupdown or netplan configuration files)

returns {ip, subnet} if the config string is valid; raises otherwise.

iex> IP.Subnet.config_from_string!("10.0.0.4/24")
{{10, 0, 0, 4}, %IP.Subnet{routing_prefix: {10, 0, 0, 0}, bit_length: 24}}
