An SRV record is a DNS record, which is used to point a domain to a third-party server and employ it for some service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is set up, you are able to specify an Internet Protocol that the domain will use and the port, which is to be employed to connect to the remote server. Additionally, provided that you have several SRV records for the exact same service, you'll be able to set various priorities and weights for every one of them, in order to send out the load between several machines. Such a record will permit you to employ the same domain address or subdomains under it with different providers, so you could use it for various purposes even if you are not able to get all services from a single provider.
