That's the default randomly-generated hexadecimal Tailnet name if you dont ever change it to a named one.[0]

You have to go to the DNS pane in the console dashboard[1] and click "Rename tailnet..." to get presented with 4 randomly-selected combos you can choose from, or re-roll for 4 more (infinitely).

Potentially not worth it if you already have an established tailnet with many nodes, its better to do it when first creating it.

I think they make named tailnets opt-in rather than the default to reduce wordspace exhaustion from users that create an account and poke around the dashboard for a few minutes and never visit again.
