abo = short for "abonnement", that is, "subscription" / "subscriber"
Just means its a pool of IPs assigned to users, I guess.

And there's a vietnamese ISP that was clever enough to give the same
rDNS - "localhost" - to all their IP space.  Don't know which one of
the three ISPs there does this, but as APNIC 20 is in Hanoi, I'll most
likely find that out for myself.

So its not FPT Vietnam, but one of the two other ISPs there
