An SRV record is a DNS record, that is used to point a domain name to a third-party server and use it for a service different from a site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you can specify an Internet Protocol that the domain address will use and the port, which will be employed to connect to the remote server. Additionally, in case you have many SRV records for the exact same service, you'll be able to set various priorities and weights for every single one of them, in order to spread the load between several machines. Such a record will enable you to use the same domain address or subdomains under it with different companies, so you could use it for various purposes even if you are unable to get all of the services from one service provider.
