An SRV record is a DNS record, that is used to forward a domain to a third-party server and employ it for a service different from a website. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you can specify an Internet Protocol which the domain address will use and the port, that will be employed to connect to the remote server. Additionally, in case you have several SRV records for the same service, you could set different priorities and weights for each one of them, in order to send out the load between a number of machines. Such a record will permit you to employ the same domain name or subdomains under it with different companies, so you can use it for various purposes even if you are not able to get all of the services from a single service provider.
