An SRV record, which stands for Service record, is a DNS entry employed to identify the servers that run a specific service for a domain. Put simply, you will be able to use your Internet domain not just for a website, 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. When you set up the SRV record, you may choose what IP 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 assuming that you have a number of SRV records for the exact same service. The second option will permit you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain name for various purposes and even with different companies in case the same one can't provide all services that you need.
