What is a dynamic ip address

An IP address is a unique address used to identify a device on the Internet. The letter “I” and “P” stands for "Internet Protocol", which is the set of rules that control the format of data sent over the Internet or local network. An IP address is a series of numbers separated by dots. IP addresses are written as a set of four numbers, for example,

There are many different types of IP addresses, and here today we are only going to focus on this very important one: dynamic IP address. Now let’s begin!

What is dynamic IP address?

The definition of dynamic ip address is really simple. A dynamic IP address, as the name says, is an IP address that changes from time to time. A dynamic IP address changes in an automatic and regular way. The frequency depends on how you configure the Dynamic Host Configuration Protocol (DHCP) or Point-to-Point Protocol over Ethernet (PPPoE) that assigns dynamic IP addresses on your servers.

The ISP (Internet Service Provider) purchases a large pool of IP addresses and automatically assigns them to its customers. On a regular basis, they reassign and return the older IP addresses to the pool to be used by other customers.

The logic behind this strategy is to get more savings for the ISP. Automating the regular movement of IP addresses means that there is no need to take specific actions to reset a customer's IP address, for example, if they move to another place. There are also security benefits, because a changing IP address makes it easier for criminals to hack into the network interface.

Dynamic vs. static IP address - Who’s better?

A public IP address is the main address associated with the entire network. Although each connected device has its own IP address, they are all included in the main IP address of the network. There are basically 2 forms of public IP addresses: a dynamic IP address and a static IP address.

Just like the opposite of a dynamic IP address, a static IP address is always the same and will not change. Once the network has assigned an IP address, it remains the same.

Most of us individual people and normal companies won't need a static IP address, but if you are a company that plans to host your own server, then you need to have a static IP address. This is because a static IP address helps make sure that linked websites and e-mail addresses have a constant IP address, which is critical if you want other devices to be able to find you predictably on the Web.

Why should you use a dynamic IP address?

Now you already know the difference between a dynamic IP address and a static IP address, so here comes the most important question: Which one is better? Which one is more suitable for me?

Well, the answer is very easy, you need to use a dynamic IP address. And here are the benefits of dynamic ip address:

1. Much lower cost

Compared to a static IP, if you use a dynamic IP, you usually don’t have to pay extra for IP changes or local network services. And you can change your IP easily without paying anything, too.

2. More Safety

Because your dynamic IP addresses are always changing, it is more difficult for potential hackers and trackers to trace and identify your device. So it’s basically impossible to hack your IP address and get your online information. A dynamic IP address gives you an extra layer of security.

3. More convenient

When you use a dynamic IP address, the available IP address will automatically be assigned to your device, so you don’t need to set up the connection of network configurations manually, which will save you a lot of work and time. This is really helpful especially when you have a new device and need to connect it to the Internet. Just imagine you come home with a brand new computer you just bought, with a dynamic IP address, you don’t have to manually input a series of conjugations, just click on connect and you’re done. It’s just that easy.

Compared to static IP addresses, using a dynamic IP address has its advantages and of course, disadvantages. Because a dynamic IP address is always changing, it's not fully supported by most Domain Name Service Providers (DNS). In addition, you may experience increased downtime and interruptions during browsing, online gaming or banking. To solve this problem, you will need a tool like VPN to provide you a more stable connection.

How to get a dynamic IP address safely and easily?

Well, now you know why you should use a dynamic IP address, the next step is to learn how to get an dynamic ip address. As mentioned above, most ISPs already provide dynamic IP addresses, so you will get a dynamic IP address as soon as your device is connected to the network. There is no need to configure anything. But occasionally, you may experience an unstable connection because of the repeatedly changing IP addresses.

Another way, a better way to get a dynamic IP is to use a VPN with dynamic IPs. A VPN with dynamic IP addresses will allow you to use all the IP addresses assigned by a server hosted by the VPN provider.
