Currently, I run a small DNS server on my development machine to resolve development domains on my devices.
It would be super awesome, if DevKinsta included such a DNS server! 
It could be either a separate Docker container that we can manually start/enable in the settings, or added to the existing devkinsta_fpm container.
The DNS server should resolve all websites currently created in DevKinsta.
There are many details on how to set up a DNS server using the Bind9 server (which is the only one I’ve used so far).
Note: For mobile testing on iOS devices, we first need an option to choose a TLD that’s different from .local
Note: If there’s a way for me to contribute a plugin/add-on/etc for DevKisnta, I’d be happy to integrate such a DNS server. Just point me to relevant documentation on how to submit that module
