No, I don't know. This is *one* client and I bet it's the dreaded
Filezilla. It opens multiple parallel connections if you don't configure
it correctly. And then it's just a matter of how your internet connection
and gateway is setup. This is a big institution with a big IP range
(whois.ripe.net). It's not your usual type of connection, but it's nothing
wrong with it.
