An SRV record, which is short for Service record, is a DNS entry which is used to outline the servers which run a specific service for a domain name. In other words, you’ll be able to use your domain name not just for a site, 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 site with it. If you create the SRV record, you can pick what Internet Protocol it's going to employ, on which port the connection to the specific server is going to be established in addition to the priority and the weight of the record provided that you have several SRV records for the exact same service. The second option will allow you to employ different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain address for a variety of purposes and even with different providers in case the same one is not able to provide all services that you need.
