An SRV record is a DNS record, which is used to direct a domain name to a third-party server and employ it for some service different from an Internet site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is created, you can specify an Internet Protocol that the domain will use and the port, which will be used to connect to the remote server. In addition, if you have several SRV records for the very same service, you could set various priorities and weights for every one of them, so you can distribute the load between a number of machines. Such a record allows you to use the same domain name or subdomains under it with different companies, so you can use it for different purposes even if you are unable to get all services from just one provider.
