OK, I will delete that comment.

I have figured them out, but that's not the end of the story. 
I don't know how to map the XX in DhcpInfoXX to a specific interface, 
and I don't know how to determine if the interface is up. 
Once that is figured out, there is another weird hex value in DhcpInfoXX 
in which the lease times are imbedded, in seconds since 1980, 
with a 1 hour offset that I can't account for.
Considering that all of this only matters on Win95 running DHCP,
I will let it simmer on my backburner.

Yes, the locally configured domain takes precedence over the DHCP
domain. I have not figured out what happens when DHCP is running
on several interfaces, providing different domain names on each.
