An SRV record is a DNS record, which is used to redirect a domain name to a third-party server and employ it for a service different from a web site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you can specify an Internet Protocol that the domain name will use and the port, that will be employed to connect to the remote server. Moreover, provided that you have several SRV records for the same service, you are able to set different priorities and weights for each and every one of them, allowing you to distribute the load between many machines. Such a record will permit you to employ the same domain name or subdomains under it with different providers, so you could use it for various purposes even if you are unable to get all of the services from one provider.
