Tag Archives: Shared Ip

Basically nowadays, since http 1.1, one IP address can host many domain names. For examples: abc.com, def.com, ghi.com, etc are shared in one IP address like 77.898.232.10. This has been common and transparent to most users.

To know how many domains are hosted in one IP, you can reverse your IP address and use domain check. Reversing IP is the easiest way to find all the .com, .net, .org, .biz, .us, and .info domains hosted on one IP address. Enter an IP address and you will get the list of domains hosted on the same IP.

What is actually the purpose of it? It is definitely because shared IP, used for many domains, affects  your site from the purpose of SEO and website filtering issue. How is it so?

From SEO Purpose

One method done by popular search engines like google, yahoo, msn, etc of detecting a website is based on its IP address. Usually, if websites are in the same IP address, search engines will consider that it is most likely they are operated by the same individual.

So unfortunately, search engines will devalue links from web sites pointing to other web sites hosted on the same IP address. On the contrary, search engines will highly value links from web sites hosted on different IP addresses as they consider the domains are operated by different individuals.

However, an outstanding Search Engine Optimizer will be able to ensure that all of their domains are registered under different registrars with different registrants. They do not use the same template on more than one web site and erase all traces showing that their sites are operated by the same individual.

But anyway, it will be better to prepare for precautions right?!

And from Website Filtering Issue,

Usually, many domain names that are hosted within the same IP address (shared IP) will  also gain problems when there is website filtering based on IP address. Why? It is because when a website is blocked based on its IP address, it will result on overblocking of the other websites hosted under the same IP too. Shared IP host many domain names. That means if one website is blocked based on its IP, the others will get blocked too as they share the same IP.

Take as an example when abc.com contains adult contents in the websites. And when there’s website filtering to block adult sites based on IP address, the other websites in the same IP will also be blocked. No matter they have no pornography at all, they will also get the effect from overblocking as they share the same IP. I am sure you have no willing of this happening to your website.

So What?

Well, if you think your site is unimportant, then no need to consider about it. However, if your website is very critical and all your life is in it, I suggest that reversing IP is very necessary to be done to find out what other domains are hosted under that same IP, IF your site is hosted within a shared IP address.

Many have questioned about the importance of a dedicated IP for a website and why if they just use a shared IP. If you are one of them, let me help you make this clearer as “crystal”. Nevertheless, before we move on, shall we begin with the definition first?

Dedicated IP address (also called static IP) means that a website has its own IP address. So this works that either you type in your URL or the IP address number, both will take you to the same domain.

On the other hand, shared IP address means the same IP is shared for multiple websites.  Then, the web servers  will determine which website is being requested by the domain entered in the user’s browser. And if you just type in the IP address, it will bring you only to some kind of generic page instead of the specific site you are requesting.

So What’s the Importance of a Dedicated IP?

Having a dedicated IP is strongly significant, especially, when you have an e-commerce website and have to accept Credit Card payment online that seems too risky if you haven’t ensured the safety. To make it secured, you need to have your own private SSL certificate as a secure e-commerce website must have an SSL certificate to accept credit cards online. And to have private SSL certificate, a dedicated IP is needed. Since you surely do not wish to experience any Credit Card fraud, you will definitely need a dedicated IP.

Another reason to use a dedicated IP is that it is required when you’d like to use anonymous FTP. With anonymous FTP, anyone who uses the FTP software can access files in a special directory of your site. It’s called Anonymous FTP because the user’s name who tries to access remains “anonymous.” Many Web hosting providers require a static IP (dedicated IP) so that the anonymous FTP can function to work properly.

Additionally, what’s better is when your website is inaccessible and you want to access it through FTP or Web browser, you can still do it if you have a dedicated IP even when there is something like domain name propagation periods. You have no need to worry such thing when you use a dedicated IP.

Is There Anything Wrong with Shared IP?

Well actually, there is nothing wrong with shared IP. However, under certain circumstances, using a dedicated IP helps you a little bit more than using a shared IP. For example, when your website shares the same IP address with known spam or adult sites, it may raise a warning flag in search engines. Consequently, some of them may respond by banning the entire IP address from their index.

Of couse, nowadays, search engines are already able to ban anything based on a domain name instead of based on the IP address itself. However, I am sure it is much better that you prepare for precaution by using a dedicated IP for your website. Especially, when your website is a very profitable e-commerce site, which your life and business depend so much on it.

How to Get Dedicated IP?

Most hosts nowadays usually offer dedicated IPs at $2 per dedicated IP to their clients. However, I am gladly telling you that there are hosting companies that already provide free dedicated IPs to their clients. And if you want to save more but get more, I strongly recommend you to get the free ones.

Why do you need to pay for dedicated IPs when you can get them for free?
