What is an IP address? What steps are involved in mapping a computer's domain name (e.g., www.creighton.edu) to its IP address?
What will be an ideal response?
An IP address is a number, usually written as a dotted sequence such as 147.134.2.84. Special-purpose computers called domain name servers are used to store mappings between domain names and their corresponding IP addresses. When a computer sends a message to a destination such as www.creighton.edu, the sending computer first transmits a request to a domain name server, which matches the recipient’s domain name to an IP address and returns that address.
