An SRV record is a DNS record, that is used to point a domain to a third-party server and use 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, and so forth. When an SRV record is set up, you are able to specify an Internet Protocol the domain name will use and the port, that will be employed to connect to the remote server. Moreover, in case you have several SRV records for the very same service, you can set individual priorities and weights for every single one of them, so that you can send out the load between a number of machines. Such a record will allow you to use the same domain name or subdomains under it with different companies, so you could employ it for various purposes even if you are unable to get all the services from a single service provider.
