Hi Glenn,

no matter what libraries or components your port scanner employs: You really should do an ICMP prescan to rule out dead IP addresses. Only thereafter you should run a port scan on the remaining set of addresses you kept in a TList or TStringList. That way you won't suffer from aggregating timeouts.

Regards
