An SRV record is a DNS record, which is used to direct a domain name to a third-party server and use it for a service different from an Internet site. This may be a Voice-Over-IP server, a video streaming service, an instant messaging system, etc. When an SRV record is set up, you could specify an Internet Protocol the domain name will use and the port, which is to be employed to connect to the remote server. In addition, in case you have several SRV records for the exact same service, you'll be able to set individual priorities and weights for each and every one of them, so you can send out the load between many machines. Such a record will allow you to use the same domain name or subdomains under it with different companies, so you can employ it for many purposes even if you are not able to get all of the services from one provider.
