An SRV record is a DNS record, which is used to direct a domain to a third-party server and use it for some service different from an Internet site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so on. When an SRV record is created, you could specify an Internet Protocol which the domain name will use and the port, which will be used to connect to the remote server. Also, in case you have a few SRV records for the same service, you are able to set different priorities and weights for each and every one of them, in order to distribute the load between several machines. Such a record allows you to employ the same domain or subdomains under it with different companies, so you could use it for various purposes even if you cannot get all of the services from a single service provider.
