An SRV record is a DNS record, which 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 many others. When an SRV record is created, you can specify an Internet Protocol that the domain will use and the port, which will be employed to connect to the remote server. Moreover, if you have numerous SRV records for the same service, you are able to set different priorities and weights for each one of them, allowing you to distribute the load between many machines. Such a record allows you to use the same domain name or subdomains under it with different companies, so you're able to use it for different purposes even if you can't get all of the services from a single service provider.
