To help you decide which type of IP address is right for your business, here are the pros and cons of static vs. dynamic IP addresses.

If you’ve made the transition into life as an entrepreneur, don’t overlook the importance of your company’s internet strategy. One part of your IT strategy is your IP address infrastructure. Even non-techies have heard of IP addresses, but many don’t have a grasp on the specific types.

Static and dynamic are the two types of IP addresses. Chances are you know a little bit about each, but maybe you don’t know enough to choose an option you feel comfortable with. Although you can run a business on either, each has strengths and weaknesses. To help save you time, we’re breaking down the key differences between static IP and dynamic IP.

IP addresses

What is an IP address?

An internet protocol (IP) address is a unique series of numbers that’s assigned to all of your devices when they connect to the internet. It allows two devices to find and exchange information and data with each other. Since no two devices have the same IP address, configuring them manually is bound to lead to human error. Fortunately, dynamic host configuration protocol (DHCP) automates this process to make life easier for users and network administrators.

In addition to configuring IP addresses correctly, DHCP assigns the subnet mask (part of the IP network that helps determine if an IP is local or on a network). It also assigns the domain name system (DNS), which translates domain names into IP addresses, and other related configuration parameters.

Similar to real-life address systems, an IP address has two parts: the network ID (street) and the host ID (house number). This means that every online place you visit knows your exact location. Sound a little Big Brother–esque? Welcome to the internet.

But don’t go off the grid just yet. There’s an affordable and legal way to keep your internet activity away from Big Brother’s surveillance and hackers. You can change your IP address and hide your location with a virtual private network (VPN). This extra layer of security can help you surf the web in peace. No one, not even your Internet Service Provider (ISP), can look at your internet activity.

The two types of IP addresses

There are two types of IP addresses: static and dynamic. While there are advantages and disadvantages to each type, your unique business needs will determine which one is right for your organization.

What is a static IP address?

A static IP address is just that. Static. This means that when a device is assigned a static IP address, the address doesn’t change. Organizations typically choose a static IP address for its dedicated services, including VPN servers and file transfer protocol (FTP), which allows you to transfer files on various computers through a network.

Static IP pros
  • Simple server hosting: Static IP addresses allow businesses to host their own website, email, and FTP server.
  • Remote access: With the enormous advances in networking technology, it’s now easier than ever for employees to work from home, their beach vacation, or their local coffee shop. For your employees to access their computer or device remotely, they’ll need to point their devices to your static IP address.

  • Hassle-free communication: Employing a Static IP address makes communicating through Voice over Internet Protocol (VoIP) and other digital voice services more reliable. Plus, a static IP address best supports name resolution (which reconciles an IP address with a computer) across wide area networks (WANs), enabling devices to reliably communicate no matter how far apart they are.
  • Fast internet speed: Static IP addresses excel in upload and download speeds. Since speed is a top concern for businesses that frequently need to download files, it’s a great idea to have a high-speed internet service provider.
Static IP cons
  • Complex setup: One major downside is that static IP addresses are hard to set up. Not only will you have to set up the device with an IP address, but you’ll also have to manually configure your router. When choosing a business internet service provider, make sure they offer adequate support to manually configure devices.
  • Lack of security: Another downfall to using a static IP address is security. An address that never changes gives hackers a longer time to find vulnerabilities in the network. To combat this potential security weakness, consider adding security measures like a firewall.
  • Cost: A static IP address means that your server is constantly running, which can lead to a costly price tag. These costs put using a static IP address in the more expensive column compared to using a dynamic IP address. But for the convenience of having your information always readily available, it’s worth the investment.

What is a dynamic IP address?

Traditional connections (think dial-up) use dynamic IPs, meaning they can change over time. Although this type of IP address means less maintenance and fees, be prepared to run into some issues if you host servers, use VoIP, or employ remote access programs.

Dynamic IP pros
  • Automated configuration: Since most devices are configured to automatically use an available IP address, you’ll spend less time and money on maintenance.
  • Price: You likely pay a pretty penny to your business internet provider, so we understand if spending more on your internet needs is the last thing you want to do. The good news is, dynamic IP addresses won’t cost you extra.
Dynamic IP cons
  • Lacks remote access capabilities: Allowing your employees to remotely access their work computers requires them to connect to a unique IP address. Having an ever-changing one makes this nearly impossible.
  • More downtime: Dynamic IP addresses are less reliable and tend to cause the service to disconnect, so if you host web servers or make phone calls over the internet (VoIP), you may want to consider a static IP address.
