Fixed Internal IP (Fixed-IP)

IP Addresses Never Change

The biggest pain point in development: every network change means IP addresses change. Connection strings need updating, SSH configs need updating, scripts need updating.

HelpRouter completely solves this problem.

Your Address Space

Git Server:      192.168.10.1
Dev Database:    192.168.10.100
Test Device:     192.168.10.101
Build Server:    192.168.10.102

These addresses are the same in Tokyo, New York, London. They never change.

Code Never Breaks

Your Git repository address: git@192.168.10.1:/repos/project.git

Works at the office, works at client sites, works at coffee shops, works at home. Same address, works everywhere.

Database connection string: postgresql://192.168.10.100:5432/devdb

Write once, run everywhere. No environment variables needed, no config file switching.

Automation Scripts Are Reliable

Deployment scripts, test scripts, CI/CD pipelines—all automation that depends on IP addresses runs reliably.

Won’t suddenly fail because you changed WiFi. Won’t need reconfiguration because you went to a client site.

Hardware-Friendly

IoT devices and embedded boards typically have hardcoded IP addresses. HelpRouter makes these devices work anywhere.

Sensor board is always 192.168.10.101, gateway device is always 192.168.10.102. Works in the lab, works in the field.

Configure Once, Use Forever

Set up HelpRouter’s internal IP scheme once, then forget about it. All your devices, all your scripts, all your configurations remain valid forever.

This is the value of fixed IPs: making the network transparent infrastructure, not daily hassle.

Addresses don’t change, workflow doesn’t change, efficiency doesn’t change.
