Description: The DNS SRV (Service Record) is a type of record in the Domain Name System (DNS) that provides information about available services in a specific domain. Unlike other DNS records, such as A or CNAME, which focus on the IP address of a host, SRV records allow specifying the service name, the protocol used, the port where the service is located, and the priority and weight of the record. This is especially useful in environments where multiple instances of a service may be available, as it enables clients to discover and connect to the most suitable instance. SRV records are essential for applications that require dynamic service discovery, such as VoIP, instant messaging, and various other network-based services. The management of SRV records can be integrated into various DNS services, allowing users to efficiently and scalably manage their services, facilitating the configuration of distributed applications and microservices.
