An SRV record is a DNS record, which is used to redirect a domain to a third-party server and employ it for some service different from an Internet site. This may 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 could specify an Internet Protocol which the domain name will use and the port, which is to be used to connect to the remote server. Additionally, provided that you have many SRV records for the exact same service, you'll be able to set various priorities and weights for every one of them, so you're able to spread the load between many machines. Such a record will permit you to use the same domain or subdomains under it with different providers, so you're able to use it for different purposes even if you cannot get all the services from a single service provider.
