An SRV record, which signifies Service record, is a DNS entry employed to outline the servers that run a particular service for a domain name. Put simply, 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 create the SRV record, you can pick what Internet Protocol it will employ, on which port the connection to the specific server is going to be established along with the priority and the weight of the record in case that you have several SRV records for the very same service. The latter option will permit you to use different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain name for various purposes and even with different companies if the same one can't provide all services you need.
