The wiki https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller#Create_a_reverse_zone says, "For a DC with the FQDN of dc1.samdom.example.com and the ipaddress of 10.99.0.1, to add a record to the 0.99.10.in-addr.arpa ..." Is this correct or should the rDNS PTR be 1.99.10.in-addr.arpa? I just want to make sure this isn't a typeo. Thanks --Mark
It is correct as is. PTR records point to IP addresses and reverse zones get that in-addr.arpa naming. Best regards, Dave. PS: I'm also resending this one Sent with Proton Mail secure email.

From the given example '10.99.0.1', you would take the first three octets '10.99.0' and reverse them '0.99.10', add '.in-addr.arpa' to get '0.99.10.in-addr.arpa' and this would be the name for the reversezone. If you require more clients, just take less octets e.g. '10.99' would give you '99.10.in-addr.arpa' Rowland
