I was having some internet connection trouble so I opened up Wireshark to see what was going on.

Strangely I saw a DNS packet which contained the host name of my computer, the packet was sent from my machine to a public DNS server on the internet.

For some reason, my computer's host name is being sent all the way across the intertubes to a public DNS server!

Is this a setting in BT4, or is it a setting in Firefox? I wanna keep my sh** private.
