What is an SRV-record? How do I create it?

The SRV-record is a type of DNS record which defines the location of servers for specific services. It is required if you use services like SIP, XMPP, CalDAV, LDAP and others.

The SRV-record has the following format:

[_service].[_protocol].[hostname]. [TTL] [class] SRV [priority] [weight] [port] [target]

This is an example of an SRV-record:

_caldav._tcp.ninefortwo.be. 3600 IN SRV 0 5 80 caldav.ninefortwo.be

To find the SRV form in your control panel hosting control panel follow:

At the top follow ‘My Products’ > ‘DNS & forwarding management’.
In the table you will see your hosts. Click on ‘DNS & forwarding’ for the host you need to add SRV-record for.
In the vertical menu to your left, select the ‘SRV-records’ option.
You have to enter the following details in the SRV-record form:

Service: _caldav
Protocol: _tcp
Hostname: / (leave empty: because it isn’t a subdomain => it’s a root domain)
TTL: 3600
Priority: 0
Weight: 5
Port: 80
Target: caldav.ninefortwo.be
