ipv4_address_in_network(ipv4: ipv4 or string, netv4: string) -> bool

Test whether an IPv4 address is in a given subnet.

Given an IPv4 address string in dotted-quad format on the left, and a subnet
slashed-dotted-quad subnet string on the right, test whether the address on the
left belongs to the subnet on the right. Note that this function does not support the
"class" and "private" subnet network addresses on the right.

This function returns a boolean true if the address is considered part of the
subnet, or false if it isn't, or null if either address or subnet is not
properly formatted.
