Une analyse opérationnelle de deux registres urbains, de la frontière technique avec RyCE et des coûts de supervision, d’intégration, de maintenance et de traitement des exceptions.

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.
