Solution

The correct option is A Inverse domain

To find the IP address of the host when domain name is known the Inverse domain can be used.

Suppose we have a function whose inverse is . Then the domain of the inverse function is the range of and the range of the inverse function is the domain of . Illustrating Draw an invertible function on the graph. As you draw, the domain and range of your function will be shown on the x- and y-axes.

The range of the original function is all the y-values you'll pass on the graph; in this case, the straight line goes on for ever in either direction, so the range is also "all real numbers". To find the domain and range of the inverse, just swap the domain and range from the original function.

Querying DNS. Click the Windows Start button, then "All Programs" and "Accessories." Right-click on "Command Prompt" and choose "Run as Administrator." Type "nslookup %ipaddress%" in the black box that appears on the screen, substituting %ipaddress% with the IP address for which you want to find the hostname.

Alternatively referred to as a namespace, a domain namespace is a name service provided by the Internet for Transmission Control Protocol networks/Internet Protocol (TCP/IP). DNS is broken up into domains, a logical organization of computers that exist in a larger network.

Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.
