Change the IP address on your phone

As your network settings require, you may need to change or manually assign the IP address to your phone. You can set or change the IP address on your phone from the network connection menu.

Your phone supports IP version 4 (IPv4), IP version 6 (IPv6), and IPv4 and IPv6. IPv4 and IPv6 is the default setting. The IP parameters can be assigned automatically by the network, or you can set them manually.

Follow the steps in the following sections as needed to change your IPv4 or IPv6 address.

The available options in the settings vary with the network settings in your organization.

Follow these steps to change or set your IPv4 network.

If your network supports both IPv4 and IPv6, you may also need to set the IPv6 settings. For how to change IPv6 settings, see Change IPv6 settings.

TFTP server 1

Unavailable only when Alternate TFTP is disabled.

Primary Trivial File Transfer Protocol (TFTP) server that the phone uses. If you are not using DHCP in your network and you want to change this server, you must use the TFTP Server 1 option.

If Alternate TFTP is enabled, enter a non-zero value for the TFTP Server 1 option.

If neither the primary TFTP server nor the backup TFTP server is listed in the CTL or ITL file on the phone, you must unlock the file before you can save changes to the TFTP Server 1 option. In this case, the phone deletes the file when you save changes to the TFTP Server 1 option. A new CTL or ITL file downloads from the new TFTP Server 1 address.

When the phone looks for the TFTP server, the phone gives precedence to manually assigned TFTP servers, regardless of the protocol. If your configuration includes both IPv6 and IPv4 TFTP servers, the phone prioritizes the order that it looks for the TFTP server by giving priority to manually assigned IPv6 TFTP servers and IPv4 TFTP servers. The phone looks for the TFTP server in this order:

  1. Any manually assigned IPv4 TFTP servers

  2. Any manually assigned IPv6 servers

  3. DHCP assigned TFTP servers

  4. DHCPv6 assigned TFTP servers

TFTP server 2
