To make the server you operate on the nameserver select a subdomain for it and
subsitute `<thisserver>` for it and its IP address `<ip of thisserver>`.
subsitute `<servername>` for it and its IP address `<ip of server>`.
The following uses a filled in example with multiple subdomains.
It uses CNAME records as a placeholder for the ip.
In the last section the domain itself `home.server` is mapped to the ip
`192.168.178.16`.
This cannot be done with CNAME as `home.server` is already mapped as a
nameserver and assigning it multiple times is not supported.

More [DNS records](./dns.md#records) can be added.
Most importantly used and needed for [reverse proxies](./reverse-proxy.md) are
[A records](./dns.md#a-record) and [CNAME records](./dns.md#cname-record).

Note that all these have to be followed by a `.` just like

For all these records add a PTR record too.
The first part of the PTR line indicated the IP address.
The first part of the PTR line is part of the IP address.
To get the full address add it to the subnet.
In this case this server has the IP `192.168.178.15`.
An example of `/etc/bind/extra-zones/revp.178.168.192` that is compatible with
the previous examples is shown in the following.

According to your IPs and domains you may need to create multiple `revp.` or
`zone.` files and need to map them back to `named.conf.local`.
