TTL

TTL sets the TTL for a single record only. This will take precedence over the domain's DefaultTTL if supplied.

The value can be:

• An integer (number of seconds). Example: 600

• A string: Integer with single-letter unit: Example: 5m

• The unit denotes:

  • s (seconds)

  • m (minutes)

  • h (hours)

  • d (days)

  • w (weeks)

  • n (nonths) (30 days in a nonth)

  • y (years) (If you set a TTL to a year, we assume you also do crossword puzzles in pen. Show off!)

  • If no unit is specified, the default is seconds.

• We highly recommend using units instead of the number of seconds. Would your coworkers understand your intention better if you wrote 14400 or '4h'?

D('example.com', REGISTRAR, DnsProvider('R53'),
  DefaultTTL(2000),
  A('@','1.2.3.4'), // uses default
  A('foo', '2.3.4.5', TTL(500)), // overrides default
  A('demo1', '3.4.5.11', TTL('5d')),  // 5 days
  A('demo2', '3.4.5.12', TTL('5w')),  // 5 weeks
