Root hint is a DNS server configuration option which can be used to improve the performance of certain types of DNS queries. When enabled, root hint instructs the DNS server to return the root server name (the top-level domain name for the DNS system) for any requested domain name.
This can help speed up the lookup process for domain names that are not located on the local network.
Overall, root hint is a relatively lightweight configuration option that can help improve the performance of certain DNS queries. However, it should only be used in cases where it is specifically necessary.
In most cases, it is not necessary and can actually have a negative impact on performance. Therefore, it is important to carefully weigh the benefits and drawbacks of using root hint before making a decision.
