An SRV record is a DNS record, that is used to direct a domain to a third-party server and use it for a service different from a site. This could be a Voice-Over-IP server, a video streaming service, an instant messaging system, and so forth. When an SRV record is created, you can specify an Internet Protocol which the domain address will use and the port, which will be employed to connect to the remote server. Also, if you have a few SRV records for the very same service, you are able to set various priorities and weights for every single one of them, so you can send out the load between several machines. Such a record will enable you to employ the same domain or subdomains under it with different companies, so you could employ it for different purposes even if you cannot get all of the services from just one service provider.
