Raspbian now uses dhcpd5, they seem to think it makes things easier, it
might do if you are just using the rpi as a client, but it just makes
things harder for me (I am not alone, the rpi forum is littered with
'how do I set a fixed ipaddress' questions)
If you remove the dhcpd5 package, you will find that the dhcp-client
package is also installed, so you can use this for getting the
computers info via DHCP, or you can set a fixed IP etc
in /etc/network/interfaces

A dns zone is dns info is stored and is named after the dns domain, it
can be a forward or reverse zone. For instance, if your dns domain is
called 'example.com' the AD forward zone will be called 'example.com',
you will also have a forest forward zone called '_msdcs.example.com'

The reverse zone is based on your IP and netmask, if your DCs
ipaddress is 192.168.0.2, then the reversezone would be
'0.168.192.in-addr.arpa'. 

You can find out your zones with:

samba-tool dns zonelist 127.0.0.1 -U Administrator
