Can I add sub-subdomains?

[SubhrajitSain]

Hello is-a.dev Community!
I am Subhrajit Sain, aka ANW. I have requested a domain anw.is-a.dev. So can I also request for a sub-subdomain, for example, yt.anw.is-a.dev or like gh.anw.is-a.dev after I get my anw.is-a.dev domain merged into the main branch? I have seen on a similar discussion from 2022 that .'s are not available for subdomains, so is that still the case and the subdomain has to be like yt-anw.is-a.dev or can I use yt.anw.is-a.dev?
Thank you! ✌

Yes? You can always make a sub-subdomain (more known as a nested subdomain) as long as you own the main subdomain.
