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 web site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is created, you could specify an Internet Protocol that the domain will use and the port, which is to be employed to connect to the remote server. Additionally, in case you have several SRV records for the exact same service, you are able to set various priorities and weights for every single one of them, in order to send out 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 can employ it for different purposes even if you are unable to get all the services from just one service provider.
