[Samba] Questions about reverse zone

[Miguel Angel Coa M.]

Hi Guys,
I've two DC (Zentyal Samba 4.7.6) and put new DC (Centos 7, Samba
4.7.6) with additional domain controller and works fine. My question is
about reverse zone. The original DC (zentyal1 and zentyal2) have a reverse
registres
```
root at zentyal1:/etc/bind# dig +noall +answer -x 10.13.250.110
110.250.13.10.in-addr.arpa. 259200 IN PTR zentyal1.example.com.

root at zentyal1:/etc/bind# dig +noall +answer -x 10.13.250.111
111.250.13.10.in-addr.arpa. 259200 IN PTR zentyal2.example.com.
root at zentyal2:/etc/bind#
```

But the new server not have reverse registre

```
root at zentyal1:/etc/bind# dig +noall +answer -x 10.13.250.128
```

I try checks revrse zone but this not exist

root at zentyal1:/etc/bind# samba-tool dns query zentyal1
250.13.10.in-addr.arpa @ ALL -U administrator
Password for [EXAMPLE\administrator]:
ERROR(runtime): uncaught exception - (9714,
'WERR_DNS_ERROR_NAME_DOES_NOT_EXIST')

I have two questions:
1. ¿is necesary create this zone and put the new DC inside?
2. From RSAT and DNS administration the domain not have reverse zone . So,
¿where does this info come from?

Thanks.
