A resource type is a DNS record that can be used to show the domain and host names to a static IP address. When forward lookup is sent to the DNS server, DNS server searches A type resource record linked with the host name provided by the application. For example, when you type on your browser, forward lookup zone will be in query and IP address 157.166.255.19 will be given as the result, which is the IP address of the site. When a computer requests an IP address by providing a host name (which is easier to use), forward lookup zone is queried to locate the IP address of the given host name. The reverse lookup zone is queried when a computer requests a host name to a specific IP address to receive the response.įorward lookup zone contains a mapping between host names and IP addresses.
The reverse lookup zone has the IP address to host name mapping. When an IP address is requested by a computer for the name of a specific host, a query is sent to the forward lookup zone to obtain a result. Forward lookup zone is the alternative host name for IP address relations. Each time an IP address is used, the DNS translates the name into the related IP address. DNS translates domain names, which are more expressive to humans in the IP addresses associated with Internet resources to find them all over the world. Difference Between Reverse Lookup Zone and Forward Lookup Zoneĭomain Name System (DNS) is the system of nomenclature that is used by any resource connected to the Internet.
