Interface's addresses will change during 2026

The IP addresses of the technical interface's test environment (EXT) of the Incomes Register will change during the service break on February 5, 2026.

• If you use direct IP addresses on the interface, changes to the system will be required due to the change of address.
• If you use name-based IP addresses, the change will have no effect and no action is required.
