An SRV record is a DNS record, which is used to point 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 forth. When an SRV record is set up, you could specify an Internet Protocol that the domain name will use and the port, which is to be used to connect to the remote server. Furthermore, provided that you have a few SRV records for the exact same service, you could set various priorities and weights for each one of them, so you're able to send out the load between several machines. Such a record will enable you to employ the same domain or subdomains under it with different companies, so you could employ it for many purposes even if you are unable to get all the services from just one service provider.
