Static vs Dynamic IP Addresses: What's the Difference and Which One Do You Need?
If you've ever noticed your IP address changing over time, you're not alone. That's because most people are assigned a dynamic IP address, while others may need or choose a static IP address. Understanding the difference is crucial for network reliability, security, and even accessing certain services.
What Is a Static IP Address?
A static IP is a fixed address that doesn't change. It's manually assigned to a device and remains constant every time you connect to the internet
Common Uses:
What Is a Dynamic IP Address?
A dynamic IP is assigned automatically by your ISP and may change periodically. This is the default for most home and mobile users
Benefits:

How to Check What You Have
You can check your IP address using our tool. If your IP changes when you restart your router, it's likely dynamic. If it stays the same, it's probably static.
Should You Request a Static IP?
Consider requesting a static IP if you:
- Run a web or mail server
- Need stable VPN or RDP connections
- Host smart home or surveillance systems
Otherwise, for most residential users, dynamic IPs are sufficient and safer by default.
