An SRV record, which signifies Service record, is a DNS entry which is used to define the servers that run a certain service for a domain name. Basically, you’re 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, as an example, while you still have a site with it. Whenever you set up the SRV record, you can pick what Internet Protocol it's going to employ, on which port the connection to the specific server will be established as well as the priority and the weight of the record provided 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. With this type of DNS records, you may use the same domain for various purposes and even with different companies in case the same one cannot provide all services you require.
