I am trying to understand more about how the domain registration process works between the registry and the registrar. My question is when a domain name is registered by a registrar such as GoDaddy, is all the information that the registrar forwards to the TLD registry about that domain name publicly available for view on Whois or is there some information that is hidden by the registry?When a domain name is purchased with the option of 'private registrations' so that the registrar hides confidential information like address details, is that information kept private by the registrar only or does it also get passed on to the registry but flagged as private information?
Is all data about a domain name provided to a TLD registry by the registrar visible on Whois?
domains;dns;domain registration
There may be other variants but from major top-level domains, the registry receives complete set of information about the registering party.Should you go for a standard registration, you are the registering party and your information is sent entirely to the domain registry. That information is generally made public as-is.Should you go private registration, a third-party often becomes the registering party. They are the ones that officially register the domain and you get an agreement saying that they act as a proxy for you. The third-party has your information but that is not sent to the registry.GoDaddy for example uses DomainsByProxy which they actually own as a separate entity. Here is the explanation of how it works for GoDaddy.
