Unique IP Address – Why is it Important?
Hosting by admin
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 73.14.213.99.
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 address. This practice
is quite dangerous as it will expose the functionality of each website on the
server.
If your website is
sharing an IP address 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 a unique IP address = Increased stability and
reliability for your website.
By having your own
unique IP address, your website would not be affected by the other websites that
are on the same server. If a website on your server becomes IP address 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 address 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
