What is the IP address range for Class A private addresses?

• A. 172.16.0.0 to 172.31.255.255
• B. 192.168.0.0 to 192.168.255.255
• C. 10.0.0.0 to 10.255.255.255
• D. 224.0.0.0 to 239.255.255.255

Answer: (C)

The range for Class A private addresses is indeed 10.0.0.0 to 10.255.255.255. This range is designated for private use within networks and is defined by the Internet Engineering Task Force (IETF) in RFC 1918. Private IP addresses are not routable on the public internet, allowing organizations to create internal networks without the need for globally unique addresses. Class A, in particular, provides a vast number of addresses, making it suitable for very large networks. The other ranges mentioned are allocated for different classes of private addresses. The range from 172.16.0.0 to 172.31.255.255 corresponds to Class B private addresses, while 192.168.0.0 to 192.168.255.255 corresponds to Class C private addresses. The range from 224.0.0.0 to 239.255.255.255 is designated for multicast addresses, which are used for one-to-many communication rather than private addressing. Understanding these classifications helps in networking design and IP address allocation.
