Yes, but one is not permitted to reassign a NetSol host-record FQDN to a
different IP. So, it is useless for that kind of redirection.
My experience was with the host record for HUGIN.LINCEXPO.ORG =
220.127.116.11, which NetSol auto-registered as owned by Don Marti when
he cited my IP address as secondary DNS for the above-named second-leve
domain. The result was that I was blocked from administrative control
of my own nameserver, a situation not fully resolved until I stepped out
from under it by moving the machine to a new IP address.
I'll have to read the bulk of your message more attentively than I have
time for at the moment. I can't fairly comment until I can do that.

Yes, but there's no compelling reason why they should be required in the
_registry_ records, just to use allow use of a DNS server for its
intended purpose. Obviously, listing an IP address should be all that's
