Question Content Analysis:

This question tests the representation method of IP addresses using Classless Inter-Domain Routing (CIDR). The question format is:

This expression has a blank that needs to be filled.

Reference Answer: Network Prefix

Analysis Process:

  1. Basic Concept of Classless Addressing (CIDR): Classless addressing no longer uses the traditional Class A, B, C division, but flexibly divides IP addresses into two parts.

  2. Two Components of an IP Address:
    • Network Prefix: Used to identify the network
    • Host Number (Host ID): Used to identify hosts within that network
  3. Standard Representation Method:
    • Complete form: IP Address = {, }
    • In practical application, it’s usually written as: IP Address/Prefix Length (e.g., 192.168.1.0/24)

Answer Judgment:

✓ The reference answer “Network Prefix” is correct

The complete statement after filling in the blank should be:

IP Address ::= {<Network Prefix>, }

This correctly reflects the two basic components of an IP address in classless addressing.
