"Reachability" is a fast way to check if there's a potential route to the host from any of the interfaces on the machine. If the machine is connected to a properly configured router, this answer will always be yes even if the host is down or the router isn't connected to the Internet. NSURL and NSSocketPort are just network connection APIs operating at different layers of abstraction. --Kyle Sluder_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
