Revising this: if you prefer I will create A, AAAA, CNAME, or DNAME records myself for your #free ⟨fedis.net⟩ subdomain rather than NS. (I'm not sure why anyone would prefer that but I also don’t see a downside of offering it.) No MX or other records, if you want those then please take the full NS delegation.
Again, boost for visibility, I’m hoping this can be a useful if small service for aspiring self-hosts.
