Does setting up My Domain in developer edition mess with my active production org?

I’m taking the “Working with Custom Lightning Components” trailhead module, which requires that I enable My Domain.  I’m nervous about doing this.  When I set up a custom domain in the developer edition I’m using for trailhead, am I also messing with my active production org?  We have not migrated to Lightning in production, have no Lightning components, and do not have My Domain set up in production.  If I create a new domain for testing purposes in developer, would my production users then have to use that URL to log into Salesforce?

Hi Susan Ross,

As you want to do only trailhead module, I suggest you sign up for new Developer Edition using below link.

https://developer.salesforce.com/signup
 
and then complete your module here so that its no way related to your production org.

Also please refer below link for information on this.

Thanks, Sandhya. I would mark this as best answer but I do not have that option. I’ve run into this issue before - I only see “reply”, “like” and “flag”.
