DNSPropagation.net Description
This DNS propagation check can be useful if you have just switched web hosts or launched a new site and have changed the DNS Name Servers of your domain from your domain registrar. This tool will perform an IP lookup and confirm if your website has been propagated globally or not. You can speed up DNS propagation by using a good provider, such as the ones listed above. You can also improve DNS propagation by setting your DNS zone TTL to a low value. When you migrate your site and make DNS changes, you want the DNS switchover as fast as possible. You can reduce the time required to perform the migration by changing your current TTL. You must set the TTL to 600 (10 minutes). This should be done at least 24 hours prior to the migration. You can lower it to 60 (1 minute) 10 minutes before the migration.
