An SRV record is a DNS record, that is used to point 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 created, you could specify an Internet Protocol that the domain address will use and the port, which is to be employed to connect to the remote server. Moreover, if you have many SRV records for the very same service, you are able to set different priorities and weights for every one of them, allowing you to spread the load between many machines. Such a record will enable you to use the same domain or subdomains under it with different providers, so you can use it for many purposes even if you are not able to get all services from just one provider.
