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