It's an impression of mine, or maybe the .NET implementation of the net functionality isn't good??? I noticed that I can't try to resolve, let's say 10, IP simultaneously! It will run sloooooooooww!!! And it gets slower if I rise this number... Thern I can't connect to 10 IP "simultaneously", because they aren't resolved

No bug. I put a two breakpoints: one just before the resolve line, one just after. The code freezes here.

Anyone else has suspected similar things?
