Check 40 of 54 · Domain and registration
That every name server and mail server your records point to still exists and is held by someone, so nobody else can take it over.

Could you lose the domain, or part of it?
The name servers and mail servers your domain's own records name. Each is asked for an address, and one with none, outside your domain, has its domain asked of the registry. It fails only where DNS and the registry agree that domain is not registered, and a failure holds the score at 59 until it is fixed. One of the two alone costs points without holding the score.
If a name server or mail server in your records sits in a domain nobody holds, anyone can register that domain, then answer lookups for your domain or receive mail meant for you.
A failure is a finding in your result. The check is scored, so it can lower your score, and the Full Report gives every finding its severity and a fix. If the check cannot finish, it is recorded as unknown: it carries no penalty, and it is never a pass.
The free check reads your domain's own name server and mail server records; a full scan also reads the subdomains it finds. A registry that does not answer leaves the finding unconfirmed rather than failed.
Check 40 is one of 10 in Domain and registration. See it in its row on the scanner page, beside the rest of Domain and registration.
The free check includes this one and takes about 30 seconds. No account. Nothing to install.
