When deploying IoT solutions at scale, secure and reliable connectivity is essential. One key factor that often determines how easily devices can be managed and accessed remotely is the type of IP addressing they use.
At Com4, we enable customers to choose the right configuration for their IoT deployments, including when and why to use fixed (static) IP addresses. With Com4’s managed SIMs and static IP options, your devices remain always reachable, secure, and easy to manage remotely, even on mobile networks that normally block inbound connections.
What Is a Static (Fixed) IP Address?
Every IoT device that connects to the internet across 2G, 3G, 4G, and 5G networks is assigned an IP address, which serves as its unique identifier.
There are two main types of IP addresses:
- Dynamic IP: changes every time a device reconnects to the network.
- Fixed (Static) IP: remains constant, even when the device moves, reboots, or reconnects.
A static IP ensures the device always keeps the same address, enabling direct, two-way communication between your IoT endpoints and your systems or cloud platforms.
Why Choose Static IPs for IoT?
IoT deployments require more than a data plan. They need consistent, secure, and manageable connectivity. With Com4’s static IPs, you gain:
- Consistent Addressing
Each device is assigned a fixed IP that never changes, simplifying integration, monitoring, and data access. - Remote Access from Anywhere
Access and control your devices across mobile networks without complex workarounds. - Built for VPNs, Firewalls, and Cloud Integration
Seamlessly connect devices to your enterprise IT setup, supporting secure connections to VPNs, firewalls, and cloud services. - No Manual Setup Required
Static IPs are managed automatically through Com4’s infrastructure — no need for local configuration or complex static mapping.
