An SRV record is a DNS record, which is used to direct 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, etc. When an SRV record is created, you are able to specify an Internet Protocol the domain will use and the port, which is to be employed to connect to the remote server. Furthermore, if you have many SRV records for the exact same service, you could set individual priorities and weights for every single one of them, so that you can send out the load between a number of machines. Such a record will enable you to employ the same domain name or subdomains under it with different companies, so you could use it for different purposes even if you are not able to get all of the services from a single service provider.
