InterNetX is a Munich-based B2B domain registrar and DNS infrastructure provider operating since 1998, with a catalog of hundreds of TLD extensions including the adult-specific registry namespaces .xxx, .adult, .sex, and .porn. The company is a channel partner for adult TLDs and manages compliance against fraud and abuse from the point of registration. This makes it a natural fit for operators or agencies registering domains under the adult-TLD framework who want a single vendor for both acquisition and management.

The platform is built for scale rather than consumer simplicity: API-first architecture, high-volume domain portfolio tools, DNS failover, SSL provisioning, and white-label capability for agencies or hosting resellers who manage client domains. Pricing is wholesale-oriented and most competitive at volume rather than for single-domain buyers.

Best suited to larger operations or domain resellers who need a reputable EU-based registrar with explicit support for adult TLD namespaces and the infrastructure to handle portfolio-level management.
