2.8. Changing the IP-Address

You components IP Addresses can be changed in /etc/network/interfaces. The IP is configured with the address variable.

nextron@asgard:~$ sudo vi /etc/network/interfaces

auto ens32
iface ens32 inet static
address 192.0.2.7
netmask 255.255.255.0
gateway 192.0.2.254

Note

There might be a case where the name of the network interface (in this example: ens32) is different. To verify this you can run ip a and see the name of the network interface.

The new IP can be applied with the command sudo systemctl restart networking.

Make sure to update the A-Records in your local DNS Server to reflect the IP changes.

2.8.1. Verifying DNS Settings

To verify if your components are using the correct DNS Server, you can inspect the file /etc/resolv.conf:

nextron@asgard-ac:~$ cat /etc/resolv.conf
search example.org
nameserver 172.16.200.2

If you see errors in this configuration, you can change it with the following command:

nextron@asgard-ac:~$ sudoedit /etc/resolv.conf
