Understanding Private vs Public IP Addresses
It’s essential to differentiate between private and public IP addresses:
Private IP Addresses
- Assigned to devices within a local network.
- Not routable on the public internet.
Public IP Addresses
- Assigned by your ISP.
- Visible to the outside world and used for internet communication.
| Parameter | Private IP Address | Public IP Address |
|---|---|---|
| Purpose | Internal network communication | External network communication |
| Visibility | Not visible on the internet | Visible on the internet |
| Examples | 192.168.1.1, 10.0.0.1 | 73.125.187.12 |
Security Considerations
When dealing with your IP address, it’s important to be aware of the potential risks:
Protecting Your IP Address
