An SRV record, which is short for Service record, is a DNS entry that is used to identify the servers that run a certain service for a domain name. In other words, you’re able to use your domain not just for a website, 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 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 specific server is going to be established in addition to the priority and the weight of the record in case that you have several SRV records for the exact same service. The second option will allow you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain address for various purposes and even with different companies if the same one is unable to provide all services that you need.
