DHTs are nice and cool, but they don't solve the problem of "where
is that box I want to talk to", i.e. its IP address.

What they /do/ is to keep this "resolution table" somewhere out there
(think DNS, but not hierarchical, rather "randomly" shuffled).

When "your" client goes out there, it has to tell "someone" "hi, I'm
Sue and my IP address is currently so-and-so". To be able to tell
"someone", you need someone's IP address. This someone is most probably
one of the nodes taking part in the DHT party.

So "... to connect to a remote home-machine (dynamic IP) through SSH
 session but without using a third-party server (free or paid)...",
as the OP put it still seems a tall order. The only thing built into
IP (v4 or V6) is multicast. There, it's the IP router's job to forward
the information "hi, this guy/gal back there is interested in that
multicast group", but my impression is (I'd love to be corrected on
that) that consumer-grade ISPs don't want people to even know this
exists (let alone offer that without billing for an arm and a kidney).
