In order for any device to communicate it needs an IP address. The type of IP address that you’ll be most familiar with is an IPv4. This is a string of numbers, usually in a format like 18.104.22.1686 .
Every single device that connects to the internet needs an IP address and under the current format we’re limited to just 4.3 billion number combinations. Because of this limitation a static IP address doesn’t tend to be offered as standard and is only really available on specific, individually tailored connections.
A static IP address is an IP that is manually configured for a certain device, rather than it being assigned to the device. The reason that it is called a static IP is because irrespective of where the device is, the IP address doesn’t change.
What is a dynamic IP address?
The majority of devices, (especially mobile) that connect to the internet will do so using a dynamic IP address. Dynamic IP’s can be reused multiple times or assigned to a large group of devices at the same time.
Why would you need a static IP and what are its advantages?
Most devices and their users don’t need a static IP address; this is why the majority of devices we use on a daily basis are connected via a dynamic IP. However, having a static IP it means that you’re able to:
- Access your device from anywhere – A static IP makes it easier for you to remotely access your device.
- Run CCTV cameras – CCTV cameras require a static IP
- Host a website – If you want to host your own website you’ll need a static IP; otherwise it will need to be hosted on somebody else’s server.
- Run a server – It’s not just servers that host websites that need a static IP, they all do.
- Control your emails – Having a static IP gives you more control over your emails as you can set up your own server.
- Make better quality calls – Voice over IP (VoIP), is essentially using the internet to make a phone call rather than a traditional phone line. These types of calls are often better when performed using a static IP.
The negatives of a static IP address
The downside to having a static IP address is that they’re often more vulnerable to hacking. However, with the industries technology constantly developing there are now a number of fantastic security solutions available to reduce the risks of hacking.
