What is the difference between a static IP number and a Shared IP number

A Static IP Address is when a website has their very own IP Address. This means that whether you type in your URL or the IP address of your website, both will bring you to the same page.

Shared IP Address - Every web server around the world is assigned an Internet Protocol (IP) address. An example of an IP address would look something like: [126.703.4.151]. Most websites on the world wide web are hosted on shared IP addresses, meaning that one server with one IP address can hold several domain names.A shared IP Address is when multiple websites all share the same IP Address. In this case, the web server does a little bit of extra work when it receives your web request, and passes you to the correct website. Typing in the IP Address will not bring you to your desired website, under most conditions. Why do we need this? I’m sure you noticed that, based on the above definition of an IP Address, that there is a finite number of IP Addresses available before we run out completely. If every single website on the internet had it’s own IP Address, there would be no room for any new ones.
Back to our home address analogy, you might consider a static IP Address to be a stand-alone home. There is only one house who gets mail at that address. You might then consider a shared IP Address to be an apartment building. Many different households get their mail at the same location, and in turn it is distributed to the correct location.
