An SRV record, which signifies Service record, is a DNS entry which is used to outline the servers that run a certain service for a domain name. Basically, you’re able to use your domain name not just for a site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, as an example, while you still have a site with it. When you set up the SRV record, you can choose 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 very same service. The second option will permit you to use different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain address for a variety of purposes and even with different companies in case the same one is not able to provide all services you require.
