Dynamic IP Addresses

An IP address is a unique identification number assigned to every device once you sign up with an Internet Service Provider (ISP). IP means internet protocol. An IP address could be static or dynamic. A static IP address is constant while a dynamic IP address changes depending on how and where they are used.

Both static and dynamic IP addresses are issued by ISPs.

Differences between Dynamic and Static IP Address


A static IP is given by the internet service provider. Once your device is assigned a static IP address, it will remain the same until the computer dies or there is a change in the network. 

 A dynamic IP address is given by the Dynamic Host Protocol servers of the ISP. This IP address can change at any time to ensure that you stay connected to the internet. Dynamic IP address is issued to devices using a similar connection. For example at home, office or hotel, each device connected to the internet has a dynamic IP address.


A static IP address is permanent. It doesn’t change as long as you are using the same ISP.

On the other hand, the dynamic IP address changes as many times as possible to ensure that you stay connected to the internet. Every new internet session you start an on internet network, provides you with a different IP address.


A static IP address is less secure than a dynamic address. Once your devices’ IP address is exposed, you are at risk of hacking. A static IP address is like a home. For example, once a criminal follows you home, they know where you live and can come back at any time. A device with static IP address is easy to trace.

A VPN solution can help boost the security of a static IP address. Using a VPN assigns you a new IP address at a different location. Making it difficult to trace and hack you. You can even get Sweden IP via VPN when you live elsewhere.

On the other hand, a dynamic IP address is more secure.  When you have a dynamic IP address, it means that you don’t have a permanent home where hackers can trace you to.

Network Stability

A static IP address provides a more stable network connection. A static IP is easily recognizable in the network and thus will be more stable.

A dynamic IP address has a less stable connection. A few times, your dynamic IP address will face downtime as the ISP has to also offer the same to other devices. Also, it is difficult to use hosted services when their IP address keeps on changing. Thus, causing instability for users of the service.

Remote Access 

As work changes thanks to technology advances, there are more and more companies hiring remote employees. Remote employees can easily access a static IP address. They can use a VPN to enhance their security as they work remotely. 

It is difficult to access a moving target remotely. Thus, a dynamic IP address is not suitable for companies that offer remote access.

Geo-location Services

It is much easier to get geo-location services when you work with a static IP address than a dynamic address. A geo-location service, for example, weather updates are localized. Thus the service provider can give you accurate information if you are static.

For a dynamic IP address whose actual location is only known when the device is online, it may be difficult to access accurate geo-location services.


If you want to chat with people in different parts of the world using voice over internet protocol (VoIP) services, a static IP address is much better. You can use VoIP for teleconferencing video calls easily if both you and the other person have static IP addresses.

With a dynamic IP address, it will be difficult to pinpoint the location of the IP address to initiate a video call. 


When you procure your services from an ISP, the service costs more when you get a static IP address.

Using a dynamic IP address, enables you to save on how much you are charged by your ISP for the service they provide. 


A dynamic website is easy to use and connects to the next available IP address. Depending on your needs and how you use the internet, you can opt for a static or dynamic IP. Whichever you choose, remember to stay secure. This is the most important aspect of comfortable internet use.
