Fixed IP Address Option

Pre-allocation of Fixed IP Address

A fixed IP address is assigned prior to configuring connection settings, for easy and swift device settings.

What is Pre-allocation of Fixed IP Address?

Fixed (static) IP address is an IP address dedicated for your personal use. Its advantage is that the same IP address can be used on your communication devices, such as routers, every time you connect to network.

The Fixed IP Address Option service allows you to use the IP address that is automatically assigned when you make the initial connection to internet, as your fixed IP address.

With the Pre-Allocation of Fixed IP Address service, described in this page, you will be informed of your fixed IP address (either by post or by fax) before you configure connection settings for initial internet connection.

Use of the pre-allocation service will support a much easier and swifter device settings.
A fixed IPv4 address will be assigned with this optional service.
