An SRV record, which means Service record, is a DNS entry that is used to define the servers that run a specific service for a domain. In other words, you’re able to use your Internet domain not just for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have a website with it. Whenever you set up the SRV record, you can select what IP it is going to 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 assuming that you have a number of SRV records for the exact same service. The second option will allow you to use different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain address for a variety of purposes and even with different providers in case the same one cannot provide all services you require.
