Unique and Shared IP addresses-What You Need to Know

Unique and Shared IP Address

Whenever you type a website address into your browser, the address (say for example the web address: (www.domainnamehere.com) is translated into a set of numbers, known as an “IP address” (the IP stands for internet protocol). So whenever you type a domain name into your browser your computer is actually directed to the IP address that the domain name is associated with.

Every site on the internet has an IP address, and every site can be reached by typing in its IP address, with some exceptions. Some websites on the internet will be hosted on the same server, which means they will have the same IP address. So for example, two websites like www.hisname.com and www.hername.com may be hosted on the same server; in which case a person looking for one of these sites will be routed to the appropriate site by the server. In cases like this, where more than one site uses the same IP, the IP address will be known as a “Shared IP address”. If a website has its own unique IP address that no one else uses, then that IP address will be known as a “unique IP address.”

Sites with a unique IP address can easily be reached by just typing in the IP address; you cannot do the same for sites with a shared IP address, since there is no way for the server to tell what specific site you want just based on the IP.

One of the main benefits to using a unique IP address is the ability to have SSL encryption. Proper encryption is important on the internet, especially when sending important material, and this encryption can only be used by a site that has a unique IP address.
