What is a Private IP Address?
A private IP address is a type of IP address that is not routed on the Internet and is not assigned by the Internet Assigned Numbers Authority (IANA). Private IP addresses are used within a local network or a private network, such as a home network, a corporate network, or a virtual private network (VPN). They are designed to be used by devices within a private network to communicate with each other.
Types of Private IP Addresses
There are several types of private IP addresses, including:
- Class A private IP addresses (10.0.0.0 – 10.255.255.255)
- Class B private IP addresses (172.16.0.0 – 172.31.255.255)
- Class C private IP addresses (192.168.0.0 – 192.168.255.255)
- Class D private IP addresses (224.0.0.0 – 239.255.255.255) for multicasting
- Class E private IP addresses (240.0.0.0 – 254.255.255.255) for future use
