HOW TO USE MY SUB DOMAIN FOR MY BLOG

Hello, please how do i use a sub domain from another registrar with my .epizy.com domain here?

I don’t really understand you tho…
You can’t use *.epizy.com and other subdomains provided by hosting anywhere outside its.

The free subdomains we provide are locked to InfinityFree. You cannot use the free subdomains elsewhere.
