Fixed IP Address Option

Fixed IP Address Option

When a computer connects to the Internet it is assigned an IP address that uniquely identifies it as a node on the Internet. Usually every time a connection to the Internet is made a different IP address is assigned. With a Fixed IP address the same IP address will be assigned every time a connection to the Internet is established. By using a Fixed IP address, your Internet opportunities increase.

The following and more are possible when using a fixed (static) IP address:

  • Enable secure remote access to your home network.
  • Realize low-cost VPN (Virtual Private Network).
  • Useful for shops and home security. You can remotely access to your webcam with your private line.
  • Some of static IP requiring online services such as gaming and day-trading become available.
  • Enable more secure working environment with groupware such as AsaOne by applying access limitation.

If you bundle Fixed IP option in set with Asahi Net ADSL or fiber-optic connection courses along with WiMAX, you can have the Fixed IP option for free (one free static IP). Any additional IP address cost 800 yen per month. This service provides a static (fixed) IPv4 address.

Monthly Charge 800 yen < Not charged in the opening month >

* All charges shown above exclude tax.

* The initial charge is billed in the month when the provided fixed (static) IP Address is connected for the first time.

* The monthly charge starts from the next month when Fixed IP Address is used for the first time. (first month is free)
