An SRV record is a DNS record, which is used to point a domain 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 many others. When an SRV record is created, you can specify an Internet Protocol that the domain name will use and the port, which will be employed to connect to the remote server. In addition, if you have a few SRV records for the very same service, you could set different priorities and weights for each and every one of them, allowing you to distribute the load between several machines. Such a record will permit you to employ the same domain address or subdomains under it with different companies, so you could use it for various purposes even if you can't get all of the services from one service provider.
