What is the SRV record?
SRV corresponds to the abbreviation for SeRVer to help you find the availability of a particular service with a certain protocol for a domain. You can give more servers, define preferences, and specify which port the service is running.
It is similar to the record of the SRV record for the long-established MX record, in fact its generalization: it is possible to specify SRV records not only for correspondence but also for any service, which can be prioritized and weighted by parameters, and finally, what kind of protocol and port we provide given service.
A domain name may have more SRV records.
Example of the SRV record
Two typical SRV records can be seen below:
_sip._tcp.example.com. 3600 IN SRV 10 60 5060 bigbox.example.com.
_sip._udp.example.com. 3600 IN SRV 10 20 5060 smallbox1.example.com.SRV record format
