Domains have hierarchy. For example, "example.com." exists of three levels: "example.", "com." and ".". Every level can have its own registry that keeps track of domain registrations. Registrants that want to register a domain at a registry, can do this through registrars, like Yocto Onoma and its SRS.
Yocto SRS is the Shared Registration System of Yocto Onoma. For external domains, domains we aren't RSP for, we proxy the registration to the registry and will function as a registrar. For internal domains, we don’t have to proxy the registration, so we directly register the domain in our systems. For both registrars for our internal domains and resellers for internal and external domains, we provide the RRP and EPP protocols, as well as API access.
