Article ID: 3662 Published: 26 Mar 2015 Updated: 24 Sep 2019 Authored by: Crazy Domains Support
An SRV Record (Service Record) is a resource record in the Domain Name System (DNS) that indicates the location of a service using a specific destination port number and hostname. Using the SRV Record, we can move services such as VOIP or IM, from host to host easily.
The SRV Record is written in this format:
_service._protocol.owner-name ttl class priority weight port target
Refer to the table below to know what this syntax means.
| Service | The symbolic service name. Common values are _http for web services and _ftp for file transfer services. |
| Protocol | The transport protocol of the service. Common values are _tcp for the TCP and _udp for the UDP. |
| Owner Name | The domain for which this record is valid. |
| TTL | Optional field. The Time to Live for this record. For ease of use at Crazy Domains, it is filled automatically using our DNS services. |
| Class | Optional field. The Class for this record. For ease of use at Crazy Domains, it is filled automatically using our DNS services. |
| Priority | The priority of the target host. The lower the number in the priority field, the more prioritised the target is. |
| Weight | The weight of the target host. When deciding between two hosts with the same priority, the higher weight is chosen. If there are no hosts with identical priority, the weight parameter should be set to 0. |
| Port | The port that the service uses. |
| Target | The domain name of the target host. |
