An SRV record is a DNS record, which is used to point a domain name 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, etc. When an SRV record is set up, you can specify an Internet Protocol the domain will use and the port, which is to be employed to connect to the remote server. Moreover, if you have many SRV records for the very same service, you'll be able to set individual priorities and weights for each one of them, so you can 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 employ it for different purposes even if you are unable to get all of the services from a single service provider.
