A simple mapping of ethereum network IDs to Ethereum ENS addresses, when available.
The network IDs are stringified integers.
The addresses are hex-prefixed ethereum addresses.
npm install ethereum-ens-network-map --save
var ensNetworkMap = require('ethereum-ens-network-map')
web3.version.getNetwork(function (err, networkId) {
var ensAddress = ensNetworkMap[networkId]
// Initialize your client from this!
})
