An SRV record, which signifies Service record, is a DNS entry employed to identify the servers which run a particular service for a domain name. Put simply, you’ll be able to use your Internet domain not just for a website, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, as an example, while you still have an Internet site with it. If you set up the SRV record, you can pick what IP it'll use, on which port the connection to the specific server will be established in addition to the priority and the weight of the record in case that you have a number of SRV records for the exact same service. The latter option allows you to use different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain address for various purposes and even with different companies if the same one is not able to provide all services you need.
