What is the IP address range for Class A networks?

1 to 126
128 to 191
192 to 223
224 to 255

The correct answer is: 1 to 126

Class A networks are identified by IP addresses that start with a number between 1 to 126. Option B is incorrect because it falls within the range for Class B networks. Option C is incorrect because it falls within the range for Class C networks. Option D is incorrect because it falls within the range for Class D and E networks, which are reserved for special purposes and not used for public networks. therefore, A is the appropriate answer for IP address range for Class A networks.
