Manual IP Change Steps - 192.168.11.4

Last Updated: 2026-01-14
Status: Active Documentation Current IP: 192.168.0.23
Target IP: 192.168.11.4

Quick Steps

Step 1: Edit Netplan Configuration

# Find netplan config file
ls /etc/netplan/*.yaml

# Edit the config file (replace with actual filename)
sudo nano /etc/netplan/50-cloud-init.yaml
# or
sudo nano /etc/netplan/01-netcfg.yaml

Step 2: Update Configuration

Find the eth0 section and update it:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
        - 192.168.11.4/24
      gateway4: 192.168.11.1
      nameservers:
        addresses:
          - 192.168.11.1
          - 8.8.8.8

Important: Keep the existing structure, just update the eth0 section.

Step 3: Apply Changes

# Validate configuration
sudo netplan try --timeout 5

# If validation succeeds, apply permanently
sudo netplan apply

Step 4: Verify

# Check new IP
ip addr show eth0

# Should show: inet 192.168.11.4/24

# Test gateway
ping -c 3 192.168.11.1

# Test ml110
ping -c 3 192.168.11.10

Complete Example Config

If your current config looks like this:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      dhcp4: true

Change it to:

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
        - 192.168.11.4/24
      gateway4: 192.168.11.1
      nameservers:
        addresses:
          - 192.168.11.1
          - 8.8.8.8

Troubleshooting

If netplan apply fails:

Check syntax:
```
sudo netplan --debug apply
```
Validate YAML:
```
sudo netplan try --timeout 5
```
Check logs:
```
journalctl -u systemd-networkd
```

If IP doesn't change:

Restart network:

sudo systemctl restart systemd-networkd

Check interface:
```
ip link show eth0
```

Bring interface down/up:

sudo ip link set eth0 down
sudo ip link set eth0 up

Reverting Back

To revert to original IP (192.168.0.23):

network:
  version: 2
  renderer: networkd
  ethernets:
    eth0:
      addresses:
        - 192.168.0.23/24
      gateway4: 192.168.0.1
      nameservers:
        addresses:
          - 192.168.0.1
          - 8.8.8.8

Then:

sudo netplan apply
