SRV record

SRV Record

When would SRV records be used?

[SRV records are used to identify that a server uses a service, commonly seen in Microsoft system directory management]

How to add an SRV record

A. In the Host record field, the format is: service name.protocol type

For example: _sip._tcp

B. The record type is SRV.

C. Line type (by default it is required; otherwise some users may be unable to resolve)

D. The corresponding value format is: priority  weight  port  hostname

For example: 0 5 5060 sipserver.example.com.

After the record is generated, a "." will be automatically appended after the domain name. This is normal. On some platforms, hostname is written as target.

E. MX priority does not need to be filled in.

F. TTL does not need to be filled in; the system will automatically generate it when adding, defaulting to 600 seconds (TTL is cache time; the smaller the value, the faster the modified record takes effect in various locations).
