If you just edited or added a new DNS record in your DNS Zone Editor, you may need to wait up to 24 hours for the change to fully propagate, but sometimes changes become visible within just a couple of hours!
NOTES:
After the propagation is completed, don’t forget to flush DNS Cache to see your website
If you updated an NS or A record and pointed your domain to Hostinger, you can use preview URL or edit the hosts file to perform changes
