An SRV record, which means Service record, is a DNS entry that is used to identify the servers that run a specific service for a domain. In other words, you’ll be able to use your domain name not just for an Internet site, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, for instance, while you still have a website with it. When you set up the SRV record, you can choose what Internet Protocol it is going to use, 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 there are several SRV records for the exact same service. The second option will enable you to employ different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain name many different purposes and even with different companies if the same one is not able to provide all services you need.
