Hi Paolo,
Yes, it is synchronous, are you experiencing any delays making the
call? The only thing that should slow that method is the lookup if you
hand it a domain name instead of an ip. I suggest resolving the domain
name on a separate thread (or when starting the app) and then pass in
a resolved InetAddress using openSocket(InetAddress inetAddress, int
port) instead.
Sincerely,
Christoffer
