An SRV record is a DNS record, which is used to point a domain name to a third-party server and employ it for some service different from a website. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is created, you could specify an Internet Protocol the domain name will use and the port, which is to be used to connect to the remote server. In addition, in case you have numerous SRV records for the same service, you can set individual priorities and weights for each and every one of them, so that you can send out the load between many machines. Such a record will enable you to use the same domain or subdomains under it with different providers, so you're able to employ it for many purposes even if you are unable to get all services from a single provider.
