# bind9
This repo details the configuration for BIND DNS on Ubuntu 22.04.
You can set up your own DNS server by following this [guide](https://www.cherryservers.com/blog/how-to-install-and-configure-a-private-bind-dns-server-on-ubuntu-22-04]).

The basic configuration is as below:

1. Install bind9 and check its status
```bash
apt update -y && apt upgrade -y
apt install bind9 bind9utils bind9-doc -y
sudo systemctl status bind9
```

2. Edit `/etc/bind/named.conf.options` and check its syntax with `named-checkconf /etc/bind/named.conf.options`. There should be no output.

3. Edit `/etc/bind/named.conf.local` and check its syntax with `named-checkconf /etc/bind/named.conf.local`. There should be no output.

4. Create a directory for your zone files with `mkdir /etc/bind/zones` and create your zone file in it as `/etc/bind/zones/example.com`. Replace `example.com` with your domain name.

5. Check its syntax with `named-checkzone example.com /etc/bind/zones/example.com`.

6. Restart bind9 with `sudo systemctl restart bind9`.
