I would like to remove IP address blocking for HULFT Square at a connection destination

Question

A connection destination from HULFT Square has implemented IP address blocking.
If I would like to allow connections from HULFT Square, what IP address should I register at the connection destination?

Answer

If you would like to remove IP address blocking for HULFT Square, please register the global IP addresses that can be checked in [ORGANIZATION] > [System Information] on the HULFT Square website.

Please note that HULFT Square is redundant with two AZs on AWS, so there are two global IP addresses.
In the event of an AZ failure, the IP address of the unaffected AZ will be automatically switched to, so please register both IP addresses at the connection destination.
