Step-by-Step Instructions

For Debian Servers using /etc/network/interfaces (Traditional Setup):

(Typically default for Debian 10, 11, and sometimes 12 if manually configured.)

1. Access the server via SSH or IPMI Console.
2. Open the network interfaces file:

sudo nano /etc/network/interfaces

1. Update the static IP configuration:

Find your interface section, usually eth0 or ens18, and edit it like this:

auto eth0

iface eth0 inet static

    address 104.160.9.50

    netmask 255.255.255.0

    gateway 104.160.9.1

    dns-nameservers 8.8.8.8 8.8.4.4

Make sure the spacing is consistent.

• address: your new IP
• gateway: your new gateway
• dns-nameservers: optional but recommended (Google DNS)

1. Restart networking to apply changes:

sudo systemctl restart networking

For Debian Servers using Netplan (Rare in Debian 12 Minimal Installs):

(If /etc/netplan/ exists, your system uses Netplan.)

1. Open the netplan configuration file:

sudo nano /etc/netplan/*.yaml

1. Update the IP settings:

network:

  version: 2

  ethernets:

    eth0:

      addresses:

        - 104.160.9.50/24

      nameservers:

        addresses:

          - 8.8.8.8

          - 8.8.4.4

      routes:

        - to: default

          via: 104.160.9.1

1. Apply changes:

sudo netplan apply

Final Notes:

• Always backup your configuration file before making changes.
• Confirm your network interface name with ip a if unsure (might be eth0, ens18, etc.).
• Ensure proper YAML spacing if using Netplan (2 spaces per indent).
