An SRV record, which is short for Service record, is a DNS entry employed to define the servers which run a certain service for a domain name. Put simply, you’ll be able to use your domain not just for a website, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, as an example, while you still have an Internet site with it. Whenever you create the SRV record, you can pick what IP it'll employ, on which port the connection to the specific server is going to be established along with the priority and the weight of the record in case that you have several SRV records for the very same service. The latter option will allow you to use different machines for load balancing and redundancy. Using this kind of DNS records, you could use the same domain name for various purposes and even with different companies in case the same one is not able to provide all services you require.
