What is the IP address of the Advantest Licensing Back-Office (license.advantest.com/FNO)

Do not use the IP address to allow the access to the Advantest Licensing Back-Office at license.advantest.com. Instead of that please use DNS to allow the access to license.advantest.com.

Reason is that in January 2026 the IP address will not be fix anymore because of various reasons like using Akamai WAF for license.advantest.com (Akamai WAF is a security solution that protects web applications from online threats).

IP address used before January 2026 of the Advantest Licensing Back-Office:  8.31.43.39
