Dedicated Hosting is being Superseded with Shared Hosting

The first time you log your pc onto the internet you should be allocated an IP address that should be completely unique to your pc, dedicated hosting that should belong to just you and nobody else. Basically, this IP address is a numerical identifier that is expressed as a 32-bit numeric code, a block of four numbers, consisting of digits from 0 to 255. Each number is separated by a dot. Google is one of those web pages that has the advantage of dedicated hosting, required by this company for a variety of reasons, not least because the amount of data being fed into its servers would not be feasible on shared hosting.

Different Kinds of IP Addresses
You can either have a shared IP address or dedicated hosting. If you are fortunate enough to have dedicated hosting it means that, to get to your website you can either type in its URL [Unique Resource Locator], or you can type in the set of numbers that make up its IP address. Either way, you will be accurately directed to the website you are seeking. This is what I meant, in the first paragraph, when I explained that you ‘should’ be allocated a unique IP address, offering you dedicated hosting: it doesn’t always happen like that nowadays.

Due to the vast influx of internet users needing their own web pages, many ISPs [internet service providers] are allocating shared IP addresses. This means that, to locate the specific page you want you must type in the URL belonging to that web page. If you type in the IP address you will be directed to a generic page containing a number of web pages, all of which are sharing the same IP address. When you arrange dedicated hosting, if you expressly want a static IP address, you will have to pay a lot more for your web hosting: the median really is expressed as shared IP addresses.

Static or Shared
There is no agreed consensus of opinion in the World of SEO as to whether dedicated hosting is better than shared, although some individuals express concern that a shared IP address could affect your rankings amongst the search engines. Concern has also been raised about a website with suspect material possibly causing a ‘red light’ to flash up when a search engine alights on a shared IP address. In both cases the jury is still out, bearing in mind that, nowadays, most websites share an IP address. The liklihood of them being penalised for sharing an IP address with a site containing unsavoury web content is pretty unlikely.

Dedicated Hosting
Basically, for most websites a shared IP address is fine and is not going to lose you any custom. However, there are certain advantages to being provided with dedicated hosting, not least when you own a private SSL Certificate so that you can accept credit cards online. Nevertheless, web hosts are well aware of this problem and, rather than providing dedicated hosting are now able to provide you with shared SSL Certificates to get around that problem. Another problem that can arise is operating anonymous FTP software. This is one case when dedicated hosting is essential because, without dedicated hosting anonymous FTP software simply will not work. This latter situation, fortunately, doesn’t affect too many individuals so, unless expressly required, dedicated hosting is not essential for most internet activities.
