An SRV record helps in fetching the available information in the system. Mostly, it is used with SIP configuration, and it has a unique naming feature.
You can manage your SRV DNS records via the DNS zone editor. To add a new record choose the type of record as SRV:
If your domain is pointing elsewhere by NS records, your DNS Zone management is moved to the provider you pointed the domain to, and should be managed from there.
What to use as a Name?
The name value should follow this structure: _service._protocol, for example:
_imaps._tcpYou don’t need to include your domain name here; it will be added automatically.
What to use as Weight?
Weight allows the zone administrators to distribute the load to multiple targets (load balance). This value will usually be provided by the service or protocol you are setting up.
What to use as a Port?
The Port is the actual port of the service offered. For instance, in the case of the IMAP protocol, it could be 993.
What to use as a Target?
The Target is the server where the record will be pointing. It can be a CNAME record or an IP, for example: server.example.tld or 185.185.185.185.
What to use as a TTL?
It is recommended to leave the default TTL (Time To Live) value: 14400 seconds (four hours).
After you make any changes to your DNS zone, propagation will start, which can take up to 24 hours to complete.
