An SRV record, which stands for Service record, is a DNS entry that is used to outline the servers that run a specific service for a domain. Basically, you’re able to use your Internet domain not only for a web site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for example, while you still have an Internet site with it. When you create the SRV record, you can pick 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 assuming that you have a number of SRV records for the exact same service. The second option will enable you to employ different machines for load balancing and redundancy. Using this type of DNS records, you could use the same domain for a number of purposes and even with different companies if the same one cannot provide all services you need.
