Most UDP sockets are setup for long periods (RTP trafic), or if an application really
wants to {open/send or receive one UDP frame/close} many sockets, it already hits

By 'long period' I mean thousand of packets sent/received by each RTP session, being
voice (50 packets/second) or even worse video...Does DNS with port randomization need short lived sockets? /Benny
