Explain the following types of DNS queries:
Inverse queries
Just as with a reverse lookup, a client making an inverse query provides the IP address and requests the FQDN. However, the server does not use the in-addr.arpa domain to find the answer, and it does not query any other servers. Instead, it simply checks its own zones for the answer, and if it does not find the answer, it returns an error message. There is no way for either the server or the client to know whether the IP address is simply missing from the zones of that server, or whether the IP address does not exist. Because support for inverse queries is optional and because servers often cannot provide a definitive answer, inverse queries are of limited use.
