An SRV record is a DNS record, which is used to direct a domain name to a third-party server and employ it for a service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is set up, you are able to 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 many SRV records for the very same service, you'll be able to set various priorities and weights for each and every one of them, so you're able to spread the load between a number of machines. Such a record will permit you to use the same domain name or subdomains under it with different companies, so you can employ it for various purposes even if you cannot get all services from just one service provider.
