An SRV record is a DNS record, that is used to direct a domain to a third-party server and use it for a 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 set up, you can specify an Internet Protocol the domain will use and the port, that will be employed to connect to the remote server. Furthermore, provided that you have several SRV records for the exact same service, you are able to set different priorities and weights for every one of them, allowing you to distribute the load between several machines. Such a record will enable you to use the same domain or subdomains under it with different companies, so you're able to use it for different purposes even if you cannot get all the services from just one provider.
