How to create a subdomain for the mobile version of the site if the domain site.rf?

Question

Domain name market

Tell me please. There is a site on the site site.rf domain (in the rf zone). I want to connect a subdomain for it for the mobile version. But the question confuses how it should be done correctly, either it is m.sayt.rf or m.sayt.rf?

Answer 1

make m.site.rf since you have a Cyrillic domain.
And m.site.rf just point to m.site.rf
