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'?

  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
