An SRV record, which signifies Service record, is a DNS entry employed to identify the servers which run a specific service for a domain name. Quite simply, you’ll be able to use your domain not only for a site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for example, while you still have a site with it. When you create the SRV record, you can choose what IP it is going to employ, on which port the connection to the particular server is going to be established along with the priority and the weight of the record assuming that you have a number of SRV records for the very same service. The second option will enable you to use different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain name many different purposes and even with different companies if the same one cannot provide all services you need.
