Which of the following is a private IP address?

IP addresses are categorized into public and private addresses. Private IP addresses are reserved for use within private networks (like homes or offices) and are not routable on the public internet. This allows multiple private networks to use the same IP ranges without conflict, as long as they are not directly connected to the internet.

• 192.168.1.1 is the correct answer. It falls within the Class C private IP address range, which is 192.168.0.0 to 192.168.255.255. This range is commonly used in small to medium-sized private networks.
• 12.0.0.1 is incorrect. This is a public IP address. It does not fall into any of the designated private IP address ranges.
• 172.33.0.1 is incorrect. While 172.x.x.x can be a private range, the specific private range for Class B is 172.16.0.0 to 172.31.255.255. Since 172.33.0.1 is outside this specific range, it is considered a public IP address.
• 200.1.1.1 is incorrect. This is a public IP address. It does not fall into any of the designated private IP address ranges.
