The Domain resolution system that converts domain names into IP addresses so the browser knows how to connect.
DNS (Domain Name System) translates memorable domain names into IP addresses that computers use to establish connections.
A concept that often causes confusion during operations is TTL — the duration a record is permitted to be cached elsewhere. Modifying a record does not take effect immediately for all users, but propagates gradually over a period equal to the old TTL.
Therefore, before migrating your Server or changing Provider, lower the TTL to a low level a few days in advance. Skipping this step is the most common reason why migration takes longer than planned.
