NAPTR records are most commonly used for applications in Internet telephony - in the mapping of servers and user addresses in the Session Initiation Protocol (SIP).
The combination of NAPTR records with Service Records (SRV) allows the chaining of multiple records to form complex rewrite rules which produce new domain labels or uniform resource identifiers (URIs).
The NAPTR record has the following look in your ClouDNS Control Panel:
|hostname.com||NAPTR||1 1 "" "123" "regular" .||3600|
In order to create a new NAPTR record, go to your control panel, click on the DNS zone at the Dashboard and from the button "Add new record" you can start adding the record. Here are example DNS record settings:
TTL: 1 Hour
Order: (from 0 to 65535)
Preference: (from 0 to 65535)
Flag: (empty or U, S, A,P)
Protocol Resolution Service: from 0 to 32 symbols
Regular Expression: someregex
Note: The Regular Expression and the Replacement cannot be used both or left empty.
ClouDNS supports NAPTR records for the all primary and secondary dns zones, both for domain and reverse dns zones.
