These touch none of the stored dataset — no apex, no indexing, no waiting for a refresh. Ask a question about a name, a certificate, a URL or a schedule and get the answer straight back.
Resolver and registry hosts are fixed constants, and a host or URL you name is dialled through a guard that refuses private and non-routable addresses and re-checks every redirect — so these cannot be pointed at an internal network. Use them against systems you are authorised to assess.
