I wanted to cast the domain (www.kookimasters.com.mx) and the page I have done for index.html is not being seen as a normal external user. why i cannot see it?
It appears you're using these nameservers:
dns1.servicios-nic.com.mx
dns2.servicios-nic.com.mx
as set up at your registrar.
You've got a CNAME record for www.kookimasters.com.mx, which points to web1.servicios-nic.com.mx, which most likely is not set up to host your domain. You should NOT have both a CNAME and an A record for one resource; instead just a CNAME which points to your server hosting your domain, or an A record.
