IP addresses assigned to users in Rotterdam are allocated by KPN, Ziggo, and T-Mobile NL, each of which manages its own blocks of IPv4 and IPv6 addresses. IP address blocks in Netherlands are allocated through RIPE NCC (Réseaux IP Européens Network Coordination Centre), the regional internet registry for Europe, the Middle East, and parts of Central Asia. RIPE's public database allows anyone to look up which ISP owns a particular IP range — this is what powers IP geolocation services.

When you connect to the internet in Rotterdam, your ISP assigns you either a dynamic or static IP address. In smaller cities, ISPs sometimes allocate IP blocks that cover a broader geographic area, which can cause your IP to geolocate to a nearby larger city rather than Rotterdam specifically. Check your current IP and its associated location using our My IP Address tool, or look up any IP with our IP lookup.

As an EU resident in Rotterdam, you benefit from the General Data Protection Regulation (GDPR), one of the strongest privacy frameworks in the world. GDPR requires ISPs like KPN to obtain clear consent before processing your personal data, and gives you the right to access, correct, or delete your information. Despite these protections, your IP address is still visible to every website you visit unless you use additional privacy measures.

To protect your privacy while browsing from Rotterdam, consider using a trusted VPN service that encrypts your traffic and masks your real IP address. Even in Rotterdam, public Wi-Fi at local cafes and public spaces can expose your data. A VPN adds a critical layer of encryption between your device and the internet. After connecting to your VPN, verify it's working properly with our VPN leak test — this checks for DNS, WebRTC, and IPv6 leaks that could expose your real Rotterdam IP address. You can also check your browser fingerprint to see how uniquely identifiable your browser is, even when using a VPN.
