dotKoeln GmbH

dotKoeln GmbH operates two city-linked generic top-level domains whose public records reveal how a registry actually works: `.koeln` and `.cologne`. The names may look like digital branding products, but their operating surface is a chain of delegated authority, DNS publication, registration state, security metadata, registrar integration, registration-data services, abuse handling, and continuity obligations. That chain is more consequential than a marketing description because every domain beneath the two endings depends on its records remaining accurate, reachable, and recoverable.
