I bought a domain, but it still doesn't work
When you register a domain name or change the DNS settings of an existing one, it won't show a new destination immediately.
Why does it happen? DNS needs to "spread." The new configurations need to be "communicated" to all servers that resolve the domain into the IP number.
The DNS activation happens at different times in different countries. To check the status of your domain's DNS, you can visit Whatsmydns.net.
Due to the rules of the registrar and information on your dashboard, it could take no more than 24 hours. Usually takes 10-20 minutes.
