• A. IP Address
• B. Web Address
• C. MAC Address
• D. Port Address

Answer 1

The Correct Option is A

In computer networking, various types of addresses are used to identify devices and resources on a network. Here, we analyze the provided information: 

Address Type	Description
IP Address	A 32-bit number, represented in decimal format as four 8-bit octets. Used to identify devices on a network.
Web Address	Also known as URL, it specifies the location of a resource on the Internet.
MAC Address	A unique identifier assigned to network interfaces for communications at the data link layer.
Port Address	An endpoint in the transport layer used to distinguish different applications or services on a device.

The number 140.168.220.200 fits the description of an IP Address. This is confirmed by its representation as four decimal values, each between 0 and 255, compliant with the IPv4 standard. Therefore, the correct classification of 140.168.220.200 is an IP Address.

Answer 2

The number 140.168.220.200 is called an IP Address.

Additional Context:

IP Address Definition (1):

• A 32-bit (IPv4) or 128-bit (IPv6) numerical label
• Identifies network interfaces for communication
• Format: Four 8-bit octets (0-255) separated by dots (IPv4)
  
  Comparison with Other Options:
• Web Address (2): Human-readable URLs (e.g., www.example.com)
• MAC Address (3): Hardware identifier (48-bit, hex format like 00:1A:2B:3C:4D:5E)
• Port Address (4): 16-bit number (0-65535) for application-level addressing    

Correct Answer: (1) IP Address
