# Public and Private IP

### Public IP

* The Public IP Address of a system is the IP address that is used to communicate outside the network. A public IP address is basically assigned by the ISP (Internet Service Provider). 
* Public IP Addresses can be traced back to the Internet Service Provider that can easily trace the geographical location.

#### Public IP Types

1. Static IP

Static Addresses are those addresses that do not change with time.

2. Dynamic IP

Dynamic IP Addresses are addresses that change over time.

### Private IP

* The Private IP Address of a system is the IP address that is used to communicate within the same network. 
* Using private IP data or information can be sent or received within the same network. 
* The router basically assigns these types of addresses to the device. 
* These things make Private IP Addresses more secure than Public IP Addresses.
* we can trace Private IP Addresses, but this happens only by using other devices on the local network. 
* Devices that are connected to the local network has private IP Address and this can only be visible to the devices that are connected within that network. 
* But it can’t be seen online as it happens in public IP Addresses.
