Service Details

See the following Fixed IP Address Option page for service details.

Contract change during the use of fixed IP address

If you are subscribed to the Fixed IP Address Option with IPv4 Connection (PPPoE), you can change to IPv4 over IPv6 Connection (IPIP).
You can also change from IPv4 over IPv6 Connection (IPIP) to IPv4 Connection (PPPoE).

  • If you wish to change the connection method, please make a request for a function change on My Page.
  • The flow of function change is as written in the Steps to Start Using. You will receive an email when your request is complete. Please change your router settings when you receive this email.
  • If you make a function change, you cannot keep your current fixed IPv4 address. A new IP address will be assigned.
  • You can continue to connect with IPv4 (PPPoE) until the provision of IPv4 over IPv6 Connection (IPIP). Please change your connection settings immediately once the IPv4 over IPv6 Connection (IPIP) is provided. The same thing applies to when changing to IPv4 Connection (PPPoE).
  • You can withdraw your request for function change until the following month of the application month.
  • If you are changing to IPv4 over IPv6 Connection (IPIP) and Asahi Net is unable to confirm whether you have started the use of IPv6 Connection Feature or not by the following month of the application month, your request for function change will be canceled.
  • Request for function change does not incur any charge.

*All charges shown on this page include tax.
