ITPEC IP April 2025 Question 32
ITPEC IP April 2025 — Question 32 of 100
10.123.45.67 — it has the dotted-decimal form of an IPv4 address.
An IPv4 address is 32 bits represented as four decimal octets separated by periods. Each octet must be between 0 and 255. The four values 10, 123, 45, and 67 all satisfy that requirement.
Answer (c)
Why not others:
- (a) resembles a hexadecimal MAC address, which identifies a network interface at the data-link layer
- (b) is formatted like a telephone number
- (d) is a URL containing a scheme, host name, and path separator, not a numeric IP address
Key rule: Recognize IPv4 by four valid decimal octets; domain names and URLs are resolved or interpreted to reach an address but are not themselves IPv4 addresses.
