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).
Why do you need a NAPTR record?
NAPTR records are commonly used with SIP in conjunction with SRV records to discover what types of services are available for a name. We can say that NAPTR record is an extension of the classic records. When someone performs a NAPTR lookup of your domain, he will find out what protocols or ports are implemented, does your domain supports SIP or some other VoIP service, and so on.
