What do I do for my linux domain members?

Also, I just checked on my domain bound W10 machine. Under

    Adapter Properties -> Internet Protocol version 4 (TCP/IPv4) -> 
Advanced -> DNS Tab

    "Register this connector's addresses in DNS" is checked, but no go 
on the reverse search:

root at samba-dc:~# host 192.168.1.83
Host 83.1.168.192.in-addr.arpa. not found: 3(NXDOMAIN)

If nothing uses the reverse search, I'm not going to worry about it.
