@danieldeaseweitzelwalker AFAIK, they handle the .de TLD, but I don't think you'd deal with them directly most of the time. Usually you'd let your hosting company or ISP do that, since you might want to register other domains, too.
@EntropySloth Thank you. I'm just reading through right now and I see they're not a registrar, but rather the central registry.
@EntropySloth I do use cloudflare, but not as a registrar.
