If you're using sockets in conjunction with this API, remember to construct the socket using the address family from the address in IPHostEntry instead of constructing the socket first. This will ensure that the socket created is compatible in terms of IPv4/IPv6. Also, remember to cycle through the addresses in the list when attempting to connect, rather than just trying the first one and failing if that one doesn't connect. |
