Is 1.111b class xyz ok for homeserver?

Hi everyone

I posted here awhile ago about something similar but wanted to ask a follow up question.

If I got a 1.111b class xyz domain for my NAS, would that have any issues?

Its mainly just going to be so family and friends can access my jellyfin.

I saw its ten bucks for ten years on their site so its a great price. I'd rather than than 20 bucks a year.

Thank you
