net.local_addresses(type, link_local)

Returns a table of the available local addresses.

The type parameter can be either "ipv4", "ipv6" or "both", and defaults to "both" if not provided.

The link_local boolean parameter additionally returns addresses specific to the local area, which won’t be routed globally.

Example:

   > for _, ip in ipairs(net.local_addresses()) do
   >> print(ip);
   >> end
   192.168.0.1
   2001:db8::1

   > for _, ip in ipairs(net.local_addresses("ipv6", true)) do
   >> print(ip);
   >> end
   2001:db8::1
   fe80::1

net.pton(address)

Converts an IP address from its string representation to the network- order byte representation.

For instance "127.0.0.1" will return "\x7f\x00\x00\x01".

net.ntop(address)

Converts an IP address from its network-order byte representation to the string representation.
