An SRV record is a DNS record, which is used to point a domain to a third-party server and use it for a service different from a web site. This can be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is set up, you could specify an Internet Protocol the domain address will use and the port, which is to be employed to connect to the remote server. In addition, in case you have several SRV records for the exact same service, you'll be able to set various priorities and weights for every single one of them, so that you can spread the load between several machines. Such a record will enable you to employ the same domain or subdomains under it with different providers, so you can employ it for many purposes even if you are not able to get all the services from a single provider.
