iiinova — where your digital self keeps evolving

I know what all of these words mean except DNS…and that seems to mean I can’t understand this sentence. What am I poking?

If you have your own domain, you can change your Bluesky name to match - so mine’s @edmooredop.com instead of edmooredop.bsky.social etc

Ohhhh, that makes a bit of sense. Thanks for explaining!
