During 2026, we will migrate step by step to a new environment. This means that throughout this year there will be multiple moments when we change a number of things for services. In this article, we explain what you can do to prepare for this.
Would you like more background information about this migration? Soon we will publish a news item on Safety and resilience projects Portbase in 2026. As soon as it is available, we will link to it here.
Change of IP range
The migration results in the IP range from which we provide the services changing. For your organisation, this has an impact if you work with strict and old firewall settings. In that case, for your organisation you have whitelisted IP addresses that are allowed to communicate.
However, this is an old and also very labour-intensive way of securing. Where possible, we recommend adjusting this and not using it (any longer). If this is (still) not technically possible, then add the IP ranges below. The region mentioned is not important.
