What is an IP Address?
An Internet Protocol (IP) address is a unique number assigned to every device that connects to the internet. Your internet service provider gives your business a public IP address that identifies your network to the wider internet.
Think of it like a mailing address for your internet connection—it tells other devices where to send information.
Static IP vs. Dynamic IP
Static IP Address: A static IP address provided by your internet service provider doesn’t change over time. It stays the same no matter when or how you connect to the internet.
Dynamic IP Address: A dynamic IP address is temporary. Your internet provider assigns it to your connection automatically, and it may change periodically.
Most standard internet services use dynamic IP addresses by default because they’re easy to manage.
| Static IP | Dynamic IP |
Changes over time | No | Yes |
Best for | Remote access, hosting, devices | General use, cost savings |
Common with | Dedicated internet | Broadband |
Do You Need a Static IP Address?
For Remote Work: If your employees or systems need to securely access your office network from outside locations, a static IP ensures these connections are consistent and trusted.
For Hosting Services: If you host things like a website, email server, or other online services directly from your office location (not using a cloud provider), a static IP ensures these services remain reliably accessible to others online.
For Business Devices: If you need external access to devices like security cameras, phone systems (VoIP), or other equipment at your office, a static IP ensures these connections stay stable and uninterrupted.
If these situations don’t apply to your business, a dynamic IP is likely sufficient.
How Are Public IP Addresses Assigned?
Your internet provider assigns your public IP address when you order service:
Dynamic IPs are the default for most standard broadband internet services. They’re flexible and work well for general business needs.
Static IPs are usually included by default with dedicated internet services or available as an add-on for broadband plans. They are designed for businesses that need consistent, unchanging public IP addresses.
Choosing a Plan with Static IPs
When signing up for business internet services, your provider may offer plans that include static IP options. If you select a plan with static IPs, these addresses will be assigned to your connection when your service is installed and activated.
Update Static IPs Anytime
Most providers allow you to adjust your static IPs later, such as adding more if your needs grow.
