What are Private IP Addresses?

Private IP addresses are a specific range of IP addresses reserved for use within local networks, such as homes, offices, and schools. Unlike public IP addresses, private IPs are not accessible directly from the internet and are designed for internal communication between devices in a Local Area Network (LAN).

Private vs. Public IP Addresses

• Private IP Addresses: Assigned to devices within a LAN. They cannot be used on the internet and are managed by the router using DHCP. Example ranges include:

  

  
  
  • 192.168.0.0 to 192.168.255.255
  • 172.16.0.0 to 172.31.255.255
  • 10.0.0.0 to 10.255.255.255
• Public IP Addresses: Globally unique addresses assigned by ISPs to connect devices or networks to the internet.

Range of Private IPs Defined by IANA

The Internet Assigned Numbers Authority (IANA) reserves the following IP address ranges for private use:

• Class A: 10.0.0.0 – 10.255.255.255
• Class B: 172.16.0.0 – 172.31.255.255
• Class C: 192.168.0.0 – 192.168.255.255

These ranges are strictly for private use and cannot be used as public IPs on the internet.

Benefits of Private IP Addresses

• Enhanced Security: Private IP addresses are isolated from the internet, reducing the risk of unauthorized access and cyberattacks.
• Efficient Use of IPv4 Address Space: Private IP ranges conserve public IP addresses by enabling multiple devices to share a single public IP through Network Address Translation (NAT).
