Changes to the IP range from July 2026

During the year 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 Security and resilience projects Portbase in 2026. Once it is available, we will link to it here.

Add new IP range

The migration means that the IP range from which we provide the services will change. For your organisation, this has an impact if you work with strict and/or old firewall settings. In that case, for your organisation you have whitelisted IP addresses with which communication is allowed.

However, this is an old and also very labour-intensive way of securing. Where possible, we recommend adjusting this and not using it (anymore). If this is (not yet) technically possible, then also add the IP ranges below. The region mentioned is not important.
