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 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 set up, you are able to specify an Internet Protocol the domain address will use and the port, that will be used to connect to the remote server. Furthermore, provided that 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, so you're able to spread the load between many machines. Such a record will enable you to employ the same domain name or subdomains under it with different companies, so you're able to use it for many purposes even if you can't get all services from a single service provider.
