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:
||1 1 "" "123" "regular" .
