An SRV record is a DNS record, that is used to redirect a domain to a third-party server and employ it for a service different from a site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is set up, you are able to specify an Internet Protocol which the domain name will use and the port, which is to be employed to connect to the remote server. Furthermore, in case you have many SRV records for the very same service, you'll be able to set individual priorities and weights for each and every one of them, so you can distribute the load between a number of machines. Such a record will enable you to use the same domain address or subdomains under it with different companies, so you can use it for various purposes even if you cannot get all the services from just one service provider.
