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 a site. This can 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, which will be employed to connect to the remote server. Additionally, provided that you have many SRV records for the same service, you can set various priorities and weights for every single one of them, so that you can spread the load between several machines. Such a record will permit 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 cannot get all the services from one provider.
