# Limits and Quotas

## Limits
<!--- Template Guidance 
A table with hard system limits of the service.
The difference with quotas is that these cannot be raised at all.
--->

* Elastic IP will natively work only for incoming traffic. Outgoing traffic will still use the native instance's IP address as a source. This behavior can be partially circumvented manually with manual Elastic IPs.
* Instances associated with a managed Elastic IP will see incoming Elastic IP traffic destined to their primary interface IP address.
* With managed Elastic IPs, it is currently not possible to retrieve the health status of an instance: while the system will not direct traffic to a unhealthy instance, there is no information about which instance is in an unhealthy state.
* HTTP health checks do not follow redirects.
* Elastic IPv6 prefixes have the same limitations as Elastic IPs.
* For managed Elastic IPv6 prefixes, only the first-plus-one IPv6 address of that prefix is transparently forwarded to the associated instances.

<!--- Template Guidance 
If there are additional specific limitations, describe below the table.

## Quotas
<!--- Template Guidance 
A table with the quotas of the service.
Below is an example for SOS. Even a single line in the table is OK.
--->
Elastic IPs are initially limited to 5 per organization.

| Usage                           | Quota   |
|:------                          |:------: |
| Elastic IP adresses count       | 5       |

## Availability
EIP is available in all zones.

<!--- Template Guidance 
Only include a table if the service is NOT available in all zones.
The table should still list all zones and use checkmarks or crosses to indicate availability.
We want to avoid any doubt about whether a service is available in a given zone.
