As mobile networks shift toward distributed and cloud-native architectures, maintaining consistent device identity has become a growing challenge. Fixed public IPs once offered simplicity, but they now conflict with modern security models, increase exposure, and limit scalability. Today’s requirement is different: enterprises need stable private IP identities that persist globally, regardless of which gateway or edge location a device attaches to.
Newer mobile core designs decouple IP assignment from individual gateways, enabling devices to keep the same private address while sessions move across regions. This supports low-latency breakout, zero-trust access, and gateway-independent resilience—all without exposing devices to the public internet.
