Introduction

This how-to will show you how to add an additional public IP to your Windows 2008 Server. Many services on a server might ask for or require additional public IPs to work correctly, such as creating private name servers, websites with SSLs, email generation, splitting services to different public IPs.

Prerequisites

You must first reserve and assign an additional public IP to your Windows Server 2008. For that guide, please visit https://www.atlantic.net/community/howto/add-additional-public-ip-atlantic-net-cloud-server/
