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 may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and many others. When an SRV record is created, you could specify an Internet Protocol that the domain name will use and the port, which is to be used to connect to the remote server. Additionally, in case you have many SRV records for the exact same service, you could set different priorities and weights for every one of them, so that you can send out the load between many machines. Such a record will allow you to employ the same domain or subdomains under it with different companies, so you can employ it for various purposes even if you are unable to get all the services from one service provider.
