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 site. This can 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 could specify an Internet Protocol that the domain name will use and the port, that will be employed to connect to the remote server. Additionally, if you have several SRV records for the very same service, you can set various priorities and weights for every one of them, so that you can send out the load between a number of machines. Such a record will enable you to employ the same domain or subdomains under it with different companies, so you could use it for different purposes even if you are not able to get all the services from one service provider.
