An SRV record is a DNS record, that is used to direct a domain to a third-party server and employ it for a service different from a website. 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, that will be employed to connect to the remote server. In addition, if you have several SRV records for the exact same service, you could set individual priorities and weights for every one of them, so you can spread the load between a number of machines. Such a record will allow you to employ the same domain address or subdomains under it with different companies, so you're able to use it for different purposes even if you are not able to get all services from a single service provider.
