An SRV record, which is short for Service record, is a DNS entry which is used to define the servers that run a specific service for a domain name. Put simply, you’ll be able to use your domain name not only for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for instance, while you still have a site with it. If you set up the SRV record, you can select what Internet Protocol it is going to use, on which port the connection to the particular server is going to be established plus the priority and the weight of the record in case that you have a number of SRV records for the very same service. The latter option will allow you to use different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain address for various purposes and even with different companies if the same one is unable to provide all services you require.
