Dortmund residential proxies

What does a Dortmund IP show that a Germany IP does not?

A Dortmund IP address can show how DSW21 timetables for the eight Stadtbahn lines appear to local users. It can also check local news and ads on Ruhr Nachrichten, a daily newspaper founded in 1949.

TechnologiePark Dortmund, opened in the 1980s, hosts about 280 companies with more than 8,500 employees. Signal Iduna, Wilo and RWE-Westnetz have their headquarters in Dortmund.

• Dortmund Port is described as the largest canal port in Europe and opened with the Dortmund-Ems Canal in 1899.
• Signal Iduna Park has 81,365 places, which makes it the largest football stadium in Germany.
• TU Dortmund was founded in 1968 and has about 30,000 students.

How do I target Dortmund in the proxy username?

Append -country-de-city-dortmund to the username from your dashboard. Country and city values are always lower case.

For a multi-step check, keep one Dortmund IP with USERNAME-country-de-city-dortmund-session-dortmu1-ttl-10. Sticky sessions last up to 30 minutes (the IP can change earlier).

An IP lookup may show a nearby place such as Bochum, Lünen, Unna and Hagen instead of Dortmund: databases place suburban address blocks differently. Check the exit before you rely on it.

Dortmund is the largest city of the Ruhr, an urban area of about 5.3 million people inside the Rhine-Ruhr Metropolitan Region.

Which networks serve homes in Dortmund?

Germany's main fixed-line providers are Deutsche Telekom, Vodafone, 1&1 and O2 Telefónica (regulator: Bundesnetzagentur (BNetzA)). Deutsche Telekom: 40.6% of fixed broadband customers in Q4 2024, per the VATM market study 2025 (via Statista). Industry data, not regulator data.

DOKOM21 is a local network in Dortmund: fibre and cable ISP of the municipal group Dortmunder Stadtwerke (DSW21), serving Dortmund and nearby towns such as Unna, Hagen and Iserlohn.

This describes the local market, not the networks our pool uses at a given moment. Read the ASN of your exit with an IP lookup, or keep the exit on one network with -asn-<number> (ASN guide).

Which rules apply to checks run from Dortmund?

Two authorities matter: the Federal Commissioner for Data Protection and Freedom of Information (BfDI) nationally, and the State Commissioner for Data Protection and Freedom of Information North Rhine-Westphalia (Landesbeauftragte für Datenschutz und Informationsfreiheit Nordrhein-Westfalen, LDI NRW) for this region. The framework is GDPR + Federal Data Protection Act (BDSG). Shops in Dortmund show prices with Germany's 19% standard VAT included, which is one reason a local IP sees different totals than a foreign one. For official local data, start with the city's own Open Data Dortmund.
