resolve() - resolve an internet address to domain name, or vice versa
int resolve( string address, string callback_func );
resolve() resolves 'address', which should be an internet address in the form "127.0.0.1" or a domain name, into its domain name, or inter‐ net address. When the resolve is complete, 'callback_func' will be called in the current object. The form of the callback is: void callback(string address, string resolved, int key); 'key' will match up with the number that the call to resolve() returned. 'address' will be the domain name of the host, and 'resolved' the dotted decimal ip address. The unknown value will be 0 if the lookup failed.
