Change TCP/IP settings on Mac

On your Mac, use TCP/IP network settings to configure IPv4 or IPv6 connections, or to renew a DHCP lease.

Note: The available settings vary depending on the type of network service selected.

To change these settings, choose Apple menu > System Settings, click Network in the sidebar, click a network service, click Details, then click TCP/IP. (You may need to scroll down.)

Open Network settings for me

Option				Description
Configure IPv4				Choose your ISP’s recommended IPv4 configuration method. Using DHCP: Choose this if you receive an IPv4 address automatically from your ISP. Using DHCP with manual address: Choose this if your ISP gave you a specific IP address and uses DHCP, then enter the IP address. Manually: Choose this if you received a specific IPv4 address, a subnet mask, and a router address from your ISP, then enter those values. Off: Choose to turn off the IPv4 settings for this interface. The available options vary depending on the type of network service you’re configuring.
Configure IPv6				Choose your ISP’s recommended IPv6 configuration method. Automatically: Choose this if you receive an IPv6 address automatically from your ISP. Manually: Choose this if you received a router address, IPv6 address, and prefix length from your ISP, then enter those values. Link-local only: Choose this to limit IPv6 traffic to the local network.
Renew DHCP Lease				Renew the DHCP lease. This option is available when the service uses DHCP.
DHCP client ID (if required)				The DHCP client identifier. This option is available when the service uses DHCP.
