An SRV record is a DNS record, which is used to redirect a domain to a third-party server and employ it for a service different from a site. This may 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 the domain will use and the port, which is to be employed to connect to the remote server. Additionally, in case you have numerous SRV records for the very same service, you'll be able to set various priorities and weights for every one of them, allowing you to send out the load between several machines. Such a record will allow you to employ the same domain name or subdomains under it with different companies, so you could employ it for many purposes even if you cannot get all services from just one provider.
