    Time to Live (TTL)

    The TTL dictates the lifespan of a DNS record; a shorter time means less time to wait until the changes go into effect. TTLs are always set in seconds with a few common ones being 86400 (24 hours), 43200 (12 hours), and 3600 (1 hour).

    When you make a change to the TTL of an existing record, you need to wait for the old TTL time to pass - that is, if it had been set to 86400, you would need to wait a full 24 hours for the new setting to begin propagating everywhere.

  6. Click Add.
