Devices on your local network, such as your phone, PC, or smart TV, use private IP addresses to communicate with each other. Your router cleverly translates these private addresses to your public IP when communicating with the internet.
Here are the key differences between public and private IP addresses:
| Feature | public IP Address | Private IP Address |
|---|---|---|
| Example | 203.0.113.1, 8.8.8.8 | 192.168.1.1, 10.0.0.1 |
| Access Scope | External communication on the internet | Internal communication |
| Use Case | device need internet communication , like server , website , email server | device within a home or office network , like home network , internal company server , printer , router |
| Assigned By | Your isp | Router or network admin |
| Unique or Not | globally unique . ensure one device is identify on the internet | Unique within the LAN. Can be reused in different networks |
| Number of addresses | Limited. IPv4 addresses are running out, IPv6 provides a larger range | Relatively unlimited. Same private address can be reused in different local networks |
| Security | Exposed on the internet. Prone to external attacks, needs additional security measures like a VPN | relatively safe . Not directly expose on the internet , but still need internal network security |
| NAT needed | No . Can be route directly | Yes . need NAT to translate private ip to public ip for internet access |
| Cost | Usually requires payment to obtain a public IP address | Free, assigned internally within the local network |
