A NAPTR (Name Authority Pointer) record is a powerful and complex DNS record that enables dynamic, rule-based lookups to transform one domain or identifier into another, such as mapping a telephone number to a SIP server (VoIP) or an email address to a web service.
❗ NAPTR records are advanced and should only be used when you specifically need their functionality.
The form contains the following fields:
• Hostname: The domain this record applies to.
• Order: Processing order (lower first).
• Pref: Preference within same order (lower first).
• Flags: Next lookup type.
• Service: Service and protocol.
• RegExp: Transformation pattern.
• Replacement: Next DNS lookup target
• TTL: The time interval (in seconds) that this record may be cached before the source of the information should again be consulted. Zero values are interpreted to mean that the record can only be used for the transaction in progress, and should not be cached.
• Active: This defines whether this NAPTR record is active or not.
