An SRV record, which means Service record, is a DNS entry that is used to identify the servers that run a certain 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 even a Voice-Over-IP server, for example, while you still have a website with it. If you set up the SRV record, you can select what IP it will employ, on which port the connection to the specific server is going to be established as well as the priority and the weight of the record in case that you have several SRV records for the very same service. The second option will permit you to employ different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain address many different purposes and even with different companies if the same one is unable to provide all services you need.
