An SRV record is a DNS record, which is used to point a domain to a third-party server and employ it for some service different from a website. This could 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 name will use and the port, which will be used to connect to the remote server. Also, in case you have numerous SRV records for the exact same service, you could set various priorities and weights for each and every one of them, so you're able to distribute the load between a number of machines. Such a record will enable you to employ the same domain or subdomains under it with different companies, so you're able to use it for different purposes even if you cannot get all the services from just one provider.
