An SRV record, which means Service record, is a DNS entry which is used to outline the servers that run a specific service for a domain name. Quite simply, you will 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 an Internet site with it. Whenever you create the SRV record, you can select what IP it's going to employ, on which port the connection to the particular server will be established as well as the priority and the weight of the record assuming that you have several SRV records for the very same service. The latter option will enable you to use different machines for load balancing and redundancy. With this kind of DNS records, you can use the same domain address for a variety of purposes and even with different companies if the same one is unable to provide all services you require.
