What is “Resolve host” ?

In the context of the Internet Protocol and the Domain Name System, a reverse lookup is often referred to simply as reverse resolving, or more specifically reverse DNS lookups. Typically, DNS is used to determine what IP address is associated with a given hostname; so to reverse resolve a known IP address is to lookup what the associated hostname for it is.
