The spelling of "srv record" is relatively straightforward. The first syllable, "srv," is pronounced /ɛs ɑr ˈvi/, with an emphasis on the middle syllable. The word "record" is pronounced /rɪˈkɔrd/, with the emphasis on the first syllable. The term "srv record" refers to a type of DNS (Domain Name System) record used to map a specific hostname and port number combination to an IP address. This allows for easy communication between devices on a network.
SRV record, also known as Service record, is a type of resource record in the Domain Name System (DNS) that provides information about available services within a domain. It is used to define the hostname and port number of a specific service offered by a domain.
The SRV record is primarily used for service discovery and load balancing in network protocols, allowing clients to locate and connect to services dynamically without the need for hard-coded IP addresses. It provides a standardized way to advertise and locate services across different systems and platforms.
The SRV record consists of several fields including the following:
- Service: Specifies the name of the service using a unique identifier, such as "_http" for HTTP services or "_smtp" for email services.
- Protocol: Specifies the transport protocol used by the service, typically TCP or UDP.
- Priority and Weight: Used for load balancing purposes, where services with lower values are given higher priority and services with higher weight values are more likely to be used.
- Port: Specifies the port number on which the service is listening.
- Target (Hostname): Specifies the domain name or hostname of the server providing the service.
Overall, SRV records play an essential role in establishing connections between client applications and services by providing a standardized method of service discovery and load balancing based on DNS.
The term "SRV record" stands for "Service record". The etymology of the word is derived from the English language, where "service" refers to a function or feature provided by a system or application. In the context of DNS (Domain Name System), an SRV record is used to define the location and configuration details of services like email, messaging, voice over IP (VoIP), etc.
