[Samba] reverse DNS not working for some reason ...

[Patrick Goetz]

As per the Wiki instructions for setting up a Samba DC, I ran

   # samba-tool dns zonecreate samba-dc 1.168.192.in-addr.arpa -U 
administrator

(while samba-ad-dc was running)

on my domain controller.  Everything seems to work; I can bind W10 
machines to this domain, use RSAT, etc., but reverse DNS searches aren't 
working:

root at data2:/etc# host samba-dc
samba-dc.ea.linuxcs.com has address 192.168.1.80
root at data2:/etc# host 192.168.1.80
Host 80.1.168.192.in-addr.arpa. not found: 3(NXDOMAIN)
root at data2:/etc# host ibs100
ibs100.ea.linuxcs.com has address 192.168.1.83
root at data2:/etc# host 192.168.1.83
Host 83.1.168.192.in-addr.arpa. not found: 3(NXDOMAIN)


I'm not sure how to go about debugging this...
