Question

To resolve the domain name to an IP address would require the use of which protocol?

1) HTTP
2) DNS
3) FTP
4) SMTP

Answer 1

The protocol required to resolve a domain name to an IP address is the Domain Name System (DNS), which functions like a phonebook for the internet, translating human-friendly domain names to machine-readable IP addresses.

Step-by-step explanation:

To resolve the domain name to an IP address, the protocol required is the Domain Name System (DNS). When you enter a web address into your browser, your computer uses DNS to look up the domain name and find the corresponding IP address. This system is fundamental to the functionality of the internet, acting like a phone book that translates human-friendly domain names to machine-readable IP addresses. Other protocols like HTTP (HyperText Transfer Protocol), FTP (File Transfer Protocol), and SMTP (Simple Mail Transfer Protocol) are used for other purposes such as accessing websites, transferring files, and sending emails respectively.
