inet_ntop() extends the inet_ntoa(3) function to support multiple address families, inet_ntoa(3) is now considered to be deprecated in favor of inet_ntop().  The following address families are cur‐
       rently supported:

       AF_INET
              src  points  to  a  struct  in_addr  (in  network  byte order) which is converted to an IPv4 network address in the dotted-decimal format, "ddd.ddd.ddd.ddd".  The buffer dst must be at least
              INET_ADDRSTRLEN bytes long.

       AF_INET6
              src points to a struct in6_addr (in network byte order) which is converted to a representation of this address in the most appropriate IPv6 network address format for this address.  The buf‐
              fer dst must be at least INET6_ADDRSTRLEN bytes long.
