# How do you associate/disassociate floating IP in an instance?

### Overview

When talking about IPs, each instance can have a public/ floating IP address in addition to its private/fixed IP address. Public addresses are used to communicate with networks outside the cloud, such as the Internet, whereas private addresses are used to communicate amongst instances. An instance's private IP address is automatically assigned when it is launched and remains the same until the instance is specifically terminated.  

The floating IP addresses you can allot to a project are specified by its project quota. After a floating IP address has been assigned to a project, you can:  

* Associate or connect the floating IP address to a compute instance, where a single instance can only ever receive one floating IP address. 
* Dissociate or delete the connection between a floating IP address and a compute instance.
