What is an IP address?
An IP address is a set of 4 digits assigned to each device on a computer network. When we talk about the definition of the internet, the IP address can be reflected a numerical representation of a website address. For example, the domain google.com have the IP address 126.96.36.199.
How do IP addresses work?
When you type a domain name in your browser window, your browser will first match that domain name to an IP address. Then, it will redirect the server at that IP address.
Why would you want a unique IP address for your website?
Web sites that have unique IP addresses are steadier and more reliable.
Disadvantages of sharing an IP address:
Sharing an IP address = Higher chance of website outage
Most web hosting providers cram thousands of websites on one server. And because IP addresses are in supply, they will often have all of the websites that are on a server which shares one IP addresses. This practice is quite dangerous as it will expose the functionality of each website on the server.
If your website is sharing an IP addresses with 1,000 websites on a server and one of those websites becomes blocked or blacklisted. All 1,000 of those websites, including yours, would be blocked or blacklisted as well.
Advantages of having a unique IP address:
Having unique IP addresses = Increased stability and reliability for your website.
By having your own unique IP addresses, your website would not be affected by the other websites that are on the same server. If a website on your server becomes IP addresses blocked or blacklisted, it would not disturb your website.
The internet is running out of space
The current IPv4 address pool is almost completely used up.
It was announced in early 2011 that the last batch of IP addresses have been allocated. This last batch of IP addresses will probably be used up towards the end of 2011. The current IPv4 address system has about 4.3 billion addresses. With a growing pool of internet users and internet-connected devices, 4.3 billion IP addresses are not enough to meet today’s demand.
Fortunately, researchers have designed a new IP addresses system – IPv6. This new system has 360 undecillion IP addresses and has been available since 1999. But, it seems like the transition is slow, and we’ll be stuck with IPv4 for a while. Here’s why:
Transitioning 4.3 billion IP addresses over to the new IPv6 system will take quite some time.
Existing equipment will need to be upgraded in order to support the new IPv6 address system.
Not many Internet Service providers (ISP) support IPv6. This means that if your ISP doesn’t support IPv6, then you won’t be able to access websites hosted with IPv6 addresses.
Currently, IPv4 addresses are accessible through all ISP’s, whereas IPv6 addresses are not
