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'?

dnsconfig.js
D("example.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
  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
END);
