Private IP Address: What You Need to Know

What is a Private IP address and how is it different from a Public IP address?

Private IP addresses are commonly used within private networks, such as home or corporate networks. How do they differ from Public IP addresses?

Answer:

A Private IP address is reserved for internal use within a private network, while a Public IP address is used to communicate over the internet.

Private IP addresses, as the name suggests, are meant for private use within a closed network. This allows devices within the network to communicate with each other without being directly accessible from the internet. On the other hand, Public IP addresses are used to access the internet and communicate with devices outside the local network.

Private IP addresses are not routable on the internet, meaning they cannot be used to directly access websites or servers on the World Wide Web. They are typically used for security and privacy reasons to isolate internal network traffic from external threats.

In contrast, Public IP addresses are used to uniquely identify devices on the internet. They are assigned by Internet Service Providers (ISPs) and are essential for devices to communicate over the internet. Without a Public IP address, devices would not be able to access online services or communicate with servers outside their local network.

Overall, the key difference between Private and Public IP addresses lies in their purpose and accessibility. Private IPs are meant for internal use within a closed network, while Public IPs are used for external communication over the internet.
