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 website. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you are able to specify an Internet Protocol that the domain address will use and the port, that will be employed to connect to the remote server. Also, if you have many SRV records for the exact same service, you are able to set various priorities and weights for every one of them, so you can spread the load between several machines. Such a record will allow you to employ the same domain or subdomains under it with different providers, so you could use it for different purposes even if you can't get all services from a single service provider.
