What is a DNS SRV record?
The ‘service’ record specifies a host and port for specific services such as Voice Over IP (VOIP), instant messaging, etc.
Example of an SRV record:
| example.com | record type: | value: | TTL |
|---|---|---|---|
| @_sip._tcp.example.com. | SRV | 8080 exampledomain.com | 41200 |
In the above example, ‘_sip’ indicates the type of service, ‘_tcp’ indicates the protocol, and ‘8080’ indicates the port while ‘example.com’ is the host.
