Watchguard Network Security Practice Test

The correct choice includes private IPv4 addresses defined by the Internet Engineering Task Force (IETF) in RFC 1918. There are three ranges of IP addresses specified for private use: 1. 10.0.0.0 to 10.255.255.255 2. 172.16.0.0 to 172.31.255.255 3. 192.168.0.0 to 192.168.255.255 In this question, both 192.168.50.1/24 and 10.50.1.1/16 are indeed private IPv4 addresses, as they fall within the ranges outlined above. However, 198.51.100.1/24 is part of a block reserved for documentation and examples (not for private use), which means it cannot be assigned as a private address. The range 172.16.0.1/16 also represents a valid private address, so while the answer provided states 192.168.50.1/24 as the only correct option, both this address and the one listed as 10.50.1.1/16 are private according to the standards. Thus, while choice A
