Static IP Address on macOS (Local Network)

This guide explains how to configure a static IP address on macOS so the computer always uses the same IP address inside the local network (LAN).

A static IP provides predictable and stable local networking.
It does not affect internet connectivity, VPN addresses, or public IPs.

Supported systems

• macOS Ventura
• macOS Sonoma
• Newer macOS versions

Applies to Mac computers using:

• Wi-Fi
• Ethernet

Important notice

Configuring a static IP changes how the Mac connects to the local network.

Incorrect values may cause:

• Loss of local network connectivity
• Loss of internet access
• Inability to reach other devices on the LAN

Before continuing, make sure you know your current network information.

Required network information

Before configuring a static IP, you must know:

• Current local IP address
• Subnet mask
• Router (gateway) IP address
• DNS server addresses
• One free IP address in the same network range

If you do not know these values, follow this guide first:

Do not continue until you have this information.

Choosing a static IP address

The static IP you choose must:

• Be in the same subnet as the router
• Not be used by another device
• Preferably be outside the router’s DHCP range

Example network:

• Router IP: 192.168.1.1
• Subnet mask: 255.255.255.0
• Valid static IP: 192.168.1.50

Avoid using:

• The router IP itself
• IPs already assigned to other devices

Configure a static IP on macOS

Static IP configuration is done through System Settings.

Open network settings

1. Open System Settings
2. Go to Network
3. Select the active connection:
   • Wi-Fi (wireless)
   • Ethernet (wired)
4. Click Details… (or Advanced… depending on macOS version)

Configure TCP/IP settings

1. Open the TCP/IP tab
2. Locate Configure IPv4
3. Change the value from Using DHCP to Manually

Set the static IP configuration

Enter the following values:

• IP Address
  The static IP you chose (example: 192.168.1.50)

• Subnet Mask
  Same as your current configuration (example: 255.255.255.0)

• Router
  Router IP address (example: 192.168.1.1)

Configure DNS servers

1. Open the DNS tab
2. Add DNS servers as needed

Common options:

• Router IP (for local DNS)
• Public DNS servers:
  • 1.1.1.1
  • 8.8.8.8

The order matters. The first server is used by default.

Apply the configuration

• Click OK
• Click Apply

The network connection may briefly disconnect and reconnect.

Common problems

No internet connection

• Verify the router (gateway) IP
• Check DNS server configuration
• Ensure the IP is within the correct subnet

IP address conflict

• Another device may already be using the same IP
• Choose a different unused IP and apply again
