Using a hex-editor is easy. It's like Notepad, but deeper. You can find a good one here:

Note the official uTorrent EXEs are compressed with UPX, so you'll need to download the "uncompressed" builds or unpack them yourself using UPX or QUnpack before you can edit them.
I remove the following things in my mods:

You can replace the IPs with 000.000.000.000, and simply fill the rest with null bytes.

a)What are the IP ranges for router.utorrent.com and router.bittorrent.com?
b)If I knew them, can I just plug them into a custom peerblock list?
a. both use the same IPs: 67.215.242.138, 67.215.242.139
b. yes, you can add them to your PeerBlock blocklist and they should no longer be contacted.

a)What's the purpose of the dht.dat file? and
b)why do you need to get one from a friend?
a. the dht.dat file contains the addresses of other peers uTorrent will connect to to form part of the DHT after start-up.
b. the "router.*.com" hosts give you some peers to get you started when you've just installed uTorrent. If you're a bit paranoid, you'll block them, but then you'll be unable to bootstrap (connect) until you get your hands on a dht.dat file - so I recommend asking a friend for his. If your DHT is already working, there's nothing to worry about.

4) Do you have to do both of these methods, or would one suffice?
If you're paranoid, you should do both :lol: Personally, I only block the call-homes and don't touch the "router.*.com" addresses. But then again my country is outside the MPAA's reach for the time being.
