## Documentation

# Overview
ENSRainbow is an ENSNode sidecar service for healing millions of unknown ENS names.

Learn more at https://ensrainbow.io and https://ensnode.io.



# How to use

## Private network
Reference the `RAILWAY_PRIVATE_DOMAIN` variable connected to the ENSRainbow instance.

Connect using HTTP to the application port (default `3223`).

## Public network
For safety reasons, by default, ENSRainbow is placed in a **private** network without public Internet access.

In order to allow public access to the service, please modify the instance network configuration accordingly.

Connect to the service from outside of Railway using the [TCP Proxy](https://docs.railway.app/guides/public-networking#tcp-proxying).

Reference the `RAILWAY_PUBLIC_DOMAIN` variable connected to the ENSRainbow instance.

Connect using HTTP to the application port (default `3223`).
