An SRV record, which means Service record, is a DNS entry employed to outline the servers which run a specific service for a domain. In other words, you are able to use your Internet domain not only 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 a website with it. If you create the SRV record, you can select what IP it will employ, on which port the connection to the specific server is going to be established plus the priority and the weight of the record provided that there are several SRV records for the exact same service. The second option will enable you to employ different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain many different purposes and even with different providers if the same one is unable to provide all services that you need.
