Change dnsmasq from .dev to .local

I have followed these instructions for setting up a dnsmasq on my mac.

I originally set it up to use .dev, but now I want to change .dev to .local, however, when I try using .local instead, it doesn't work.

Even when I uninstall dnsmasq, and unload and remove the settings using launchtl, requests to .dev still work, and .local don't. I have tried restarting too.

Are these settings set automatically by apple somewhere else and being used (and always have been?)

And how can I change to using .local?

Thanks
