What is a root hint, and how are root hints used?
What will be an ideal response?
On a DNS server, a root hint is a resource record to enable a DNS server to quickly find an authoritative DNS server in a zone that is not on the DNS server and is used in particular to find an authoritative DNS server on the Internet. When a DNS server receives a query for a domain it does not recognize, it can use the root hint to find that domain on the Internet. When you configure a DNS server, there are about 15 root hints configured automatically for well-known top-level Internet domains.
