An SRV record is a DNS record, that is used to point a domain name to a third-party server and employ it for a service different from a website. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you are able to specify an Internet Protocol which the domain name will use and the port, which is to be used to connect to the remote server. Furthermore, if you have several SRV records for the very same service, you can set individual priorities and weights for each and every one of them, so that you can spread the load between a number of machines. Such a record allows you to employ the same domain or subdomains under it with different providers, so you could use it for various purposes even if you are not able to get all services from just one service provider.
