An SRV record is a DNS record, which is used to redirect a domain to a third-party server and use it for some service different from a website. 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 are able to specify an Internet Protocol which the domain address will use and the port, which is to be employed to connect to the remote server. Also, if you have a few SRV records for the exact same service, you are able to set different priorities and weights for each and every one of them, in order to send out the load between a number of machines. Such a record will enable you to employ the same domain name or subdomains under it with different companies, so you could use it for many purposes even if you are unable to get all services from one service provider.
