Static IP Address (Local Network)

This guide explains how to configure a static IP address on a local network so a computer always uses the same IP address when connected to the same LAN or router.

A static IP provides network stability and predictability inside the local network.

What is a static IP?

A static IP address is a fixed network address assigned to a device on a local network.

Unlike dynamic IP addresses (assigned automatically by the router via DHCP), a static IP does not change when:

• the device restarts
• the network reconnects
• the router restarts

Why use a static IP?

Using a static IP is recommended when:

• A device must always be reachable at the same address on the local network
• Other local devices need to connect to it reliably
• Local services depend on a fixed network address
• Network configurations reference the device by IP
• You want predictable and stable local networking

A static IP improves local network reliability, not remote connectivity.

When should you avoid a static IP?

A static IP may not be necessary if:

• The device is only used for basic internet access
• No other local devices connect to it directly
• The network environment changes frequently
• The device moves between different networks

Local network only (important)

This guide applies only to local network (LAN) IP addresses, such as:

• 192.168.x.x
• 10.x.x.x
• 172.16.x.x

It does not configure:

• Public IP addresses
• Internet-facing IPs
• VPN addresses
• ISP-level static IPs

Remote connectivity is handled separately using a VPN.

Two valid approaches

There are two correct ways to ensure a stable IP address on a local network:

1. Configure a static IP directly on the device
2. Reserve an IP address on the router (DHCP reservation)

This guide focuses on device-based static IP configuration, which works independently of the router and does not require router access.

What you need before starting

Before configuring a static IP, you should know:

• The current local IP address of the device
• The router (gateway) IP address
• The subnet mask
• One free IP address within the local network range

This information can be obtained from the device’s network settings.
