Shared vs. Dedicated IPs & Port Access

Summary

This article will explain what the differences between a Shared & Dedicated IP as well as how to open additional ports on your account.

Shared IP

Every domain name has an IP address assigned to it. An IP address is the real address of a web site or server. Domain names were developed because it is difficult to remember long IP numbers like 234.123.66.7.

In shared hosting we host several hundred web sites on one server; those same sites will share one single IP address. Instead of having a unique IP address for every domain, you share one IP address with all of the accounts on your server. The downside to shared IP’s is that some countries, like China, censor particular web sites by their IP address. If a web site they censor is on the same server as yours, and China blocks that web site using the shared IP address, then your web site and the hundreds of others on that server are also blocked. This means that any clients in China would be unable to view your site. Getting a dedicated IP address would make your web site separate so that if the shared IP address was blocked, your site wouldn’t automatically be blocked along with it.

Email:

Email will not be affected by obtaining a dedicated IP address. All email, including forwarded email, is sent out through our mail servers. Obtaining a dedicated IP address should prevent your emails from being marked as SPAM, having an ISP block the IP of the mail proxy server, or pass a reverse DNS test for places such as AOL.

However, if you upgrade your services from a shared account to a VPS, Cloud Server or a Dedicated Server then your website would have its OWN email servers and you’re email performance would not be hindered by any other client on your current server.

Dedicated IP

By purchasing a Dedicated IP your site is the only one on the Internet that will be using that unique IP address. For example, if you typed http://64.233.187.99/ into your web browsers address bar you would see Google’s web site come up. This is their dedicated IP address and no one else’s. This is their unique address on the web that has been attached to the domain name google.com. To purchase a dedicated IP address,  please contact our support team.

Program/Script Requirements

The program or script you run on your site may require a process to run longer than 10 minutes. On a shared IP address, the process will terminate at the 10 minute mark. With a dedicated IP address, processes are allowed to run for more than 10 minutes as long as they aren’t consuming too much of the server’s memory, which would result in a CPU throttling. CPU throttling can occur both on a shared and a dedicated IP address. Certain voice chat programs require a dedicated IP address before they can be setup and used. If you have a program that sends out emails every so many seconds, such as from a mailing list program like DaDa Mail, then you would need to get a dedicated IP address, if it’s going to take more than 10 minutes to send out the emails..

Port Access

In a shared hosting environment, where everyone shares the same IP, some ports must be blocked. We block access to certain ports to help avoid having security holes in the firewall, and to allow us to monitor and control customers who attempt to abuse the different services that we allow to run through these ports. The majority of processes requiring specific Port Access typically are bound to the IP address which they are running on.

On a shared IP only one service could run through a specific port from that IP. We have only opened the ports for processes which we are running on our servers (web mail, cPanel, etc.). Purchasing a dedicated IP will allow us to grant you access to the ports you will need to run your specific services on. This applies to both outbound and inbound connections running on non-standard ports. If you have a dedicated IP and require ports to be opened, please contact our support team.
