# Resolving port conflicts with a second IP

{% hint style="warning" %}
**Your ESP platform must be installed on its own IP address and can not share an IP with other applications that may cause port conflicts.**
{% endhint %}

{% hint style="info" %}
Ports needed by the ESP platform include common ports such as 80, 443, and 587, if these ports are blocked and unavailable, the platform will fail to start. 
{% endhint %}

These are the most common scenarios where a second IP may be needed for your ESP platform installation:

* You're already running a website on the server where you want to install the ESP platform. 
* You have some type of control panel software the server came pre-installed with such as CloudPanel, CPanel, or Plesk, and you don't want to remove it. 
* You're running a web-based application on the server that isn't necessarily a website but is still accessed using https\:// in a web browser. 
* You want to use the ESP platform and the MTA on the same server.

{% hint style="success" %}
**For clarity:** you can run on the same **server** as other applications using ports 80 and 443, but the platform needs its own *IP address* on that **server** in order for this to work.
