I don't know enough about this hope someone can help:
My ISP CEO suggests that this address is BitTorrent:

Is that correct?
No, he is confused.

There are no trackers involved with apt-get, although it would be a far
more efficient method (bandwidth wise). The downside is that you
probably wouldn't be able to update/upgrade your laptop at your local
library etc. because they tend to block BitTorrent traffic.
I think I remember reading about a discussion of implementing a system
where apt-get only downloads the changes to files. It wouldn't suprise
me if something like this was implemented at some point way down the
track.
I think the number one reason why Linux package management via Torrent
never took off is because it is frankly an incredibly terrible idea.
Look, peer-to-peer is a great idea on paper, but it has several huge
strikes against it:
1. ISPs hate P2P even for legitimate uses, so if a Linux distro would go
torrent on package managers those behind draconian ISPs will be out of
luck, leading to less users.
2. EVERY package will become subject to the "popularity contest" problem
in peer to peer. You'll likely have no problem installing common apps,
but if you like to use something more specialized or obscure but still
tracked in the official repository, you'll be lucky to get a decent
speed at all, to say nothing about the possibility you'll NEVER get the
package. This is why torrents are fast in theory but dreadfully slow in
practice (I have never in all my time seen a single torrent beat the
speeds of straight up downloading.)
3. It's efficient bandwidth only on the PROVIDER'S servers. Torrents are
notorious for gobbling up download bandwidth on actual people
downloading. I don't want to slow my entire network to a crawl just
downloading a kernel, thank you.
4. You're labeled a leecher just because you don't want to spend several
hours UPLOADING a package that took you upwards of half an hour to get
in the first place. If I were to install Debian via torrent I'd be
spending MONTHS clogging up my upward channels trying to get to a 1.0
ratio I'll never achieve because I'll be updating packages still.
Now, I do like the idea of updates being BINARY PATCHES to the packages
installed. The downside being that if you need to fall back to an older
version you might be out of luck if simply unpatching won't work.
