...yet another question about github pages and custom domains, sorry. I couldn't find a solution in other questions, I think that's very specific to my registrar. Also, I'm not a webmaster or sysadmin, this would be simply my online resume (CV).
I have a domain from Argentina's nic.ar registrar => mydomain.com.ar
Currently, my domain is delegated to a free web hosting where I was experimenting with. I want it to point to my current github page myuser.github.io, but I simply don't know how.
Github gave me 4 IP addresses in order to redirect:
but my registrar only accepts hostnames:
What options that are free and simple do I have to make my .com.ar domain point to my github page?
