An SRV record, which means Service record, is a DNS entry that is used to identify the servers that run a specific service for a domain. Basically, you’ll be able to use your domain not only for a website, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, for example, while you still have a website with it. If you create the SRV record, you may choose what Internet Protocol it'll employ, on which port the connection to the specific server will be established in addition to the priority and the weight of the record assuming that you have a number of SRV records for the very same service. The second option will permit you to use different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain address for a variety of purposes and even with different companies in case the same one is unable to provide all services that you need.
