Which technology allows both a URL and an IP address to refer to the same site?
A
ISP
B
GUI
C
DNS
D
HTML
Explanation: 

Detailed explanation-1: -DNS servers convert URLs and domain names into IP addresses that computers can understand and use.

Detailed explanation-2: -Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device.

Detailed explanation-3: -The Internet’s DNS system works much like a phone book by managing the mapping between names and numbers. DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser. These requests are called queries.

Detailed explanation-4: -It is not possible to provide two domain names for the same Server IP address and get two different SSL certificates (one for each domain name). Also note that the use of Host Headers (which is how you can use a single IP for more than one SSL enabled domain) is not recommended for E-Commerce sites.
