Static vs Dynamic IP: Which One Do You Have?
Every device connected to the internet has an IP address — a unique identifier that allows communication between networks. But not all IPs are the same. The two main types are static and dynamic IP addresses. Understanding which one you have helps with troubleshooting, privacy, and even setting up remote access securely.
What is a static IP?
A static IP address is a fixed number assigned to your device or network that never changes. ISPs or network administrators usually configure it manually. Static IPs are essential for hosting servers, websites, security cameras, or remote connections that require a consistent address.
- Pros: Reliable remote access, easier DNS mapping, stable server connections.
- Cons: Easier to track, potentially higher cost, more visible attack surface if security is weak.
What is a dynamic IP?
A dynamic IP address is automatically assigned by your Internet Service Provider (ISP) from a pool each time your device connects. The address can change periodically — for example, after rebooting your router or after a lease period expires.
- Pros: More private, lower cost, automatic management.
- Cons: Unsuitable for permanent hosting or services that require constant access.
Static vs Dynamic IP comparison
| Feature | Static IP | Dynamic IP |
|---|---|---|
| Assignment | Manual / fixed | Automatic via DHCP |
| IP changes | No (permanent) | Yes (periodically) |
| Best for | Servers, CCTV, business networks | Home users, general browsing |
| Security risk | Higher if unprotected | Lower — changes often |
| Cost | Usually extra | Included by default |
| Ease of setup | Manual configuration | Automatic (plug and play) |
How to check if you have a static or dynamic IP
- Go to What is My IP to view your public IP address.
- Note it, then reboot your router or reconnect to your network.
- Check your IP again on the same page. If it changed, you have a dynamic IP. If it remained identical, you likely have a static IP.
- You can also confirm by checking your router settings under “WAN” or “Internet” configuration — look for options mentioning “Static” or “DHCP”.
Which type is better?
For most users, a dynamic IP is sufficient and safer, as it offers automatic updates and more privacy. However, if you need stable remote access or run a self-hosted service, a static IP may be worth it — provided you implement proper firewall rules, VPN, and encryption.
How to secure your IP connection
- Use a VPN to mask your real IP address.
- Regularly test for DNS or WebRTC leaks.
- Keep your router firmware and connected devices up to date.
- Enable the firewall on your router and operating system.
