Is there way to create PrivateLink connection without using static IP address?

Question

Is there a way to create a PrivateLink connection without using a static IP address?
We created an NLB in our AWS environment for a PrivateLink connection between a destination system and HULFT Square, and we need to specify the static IP address of the destination system in a target group of the NLB.
However, it is difficult to specify a static IP address because the environment of the destination system uses a static IP address in few cases.

Answer

When an NLB connection destination needs to be specified as an IP address, the NLB can connect to only a static IP address, as described in the following page.
Therefore, you basically need to specify a static IP address in the NLB settings.

The Technical Support Center cannot support NLB settings, such as how to route to dynamic IP addresses.
