Did you know that you can point any domain to 127.0.0.1 and it will happily resolve to your local development environment? No more edits to /etc/hosts or complex NS server setups.
For example, if the domain of your project is example.com then you could set the A record of local.example.com to 127.0.0.1. But wait — there is more — you can have unlimited subdomains such as *.local.example.com if your DNS provider supports wildcard A records.
Here is a screenshot of the DNS setup in DigitalOcean that I use for *.wpenv.net domains:
The A record for the root level wpenv.net pointing to a GitHub IP for the repository which has the README about the domain. It is like a landing page for the service.
The important bit is the A record for *.wpenv.net pointing to 127.0.0.1.
