An SRV record is a DNS record, which is used to point a domain name to a third-party server and use it for a service different from a web site. 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 employed to connect to the remote server. Also, in case you have many SRV records for the exact same service, you are able to set different priorities and weights for every single one of them, so you're able to distribute the load between a number of machines. Such a record will permit you to employ the same domain address or subdomains under it with different companies, so you can employ it for different purposes even if you cannot get all the services from just one service provider.
