An SRV record, which means Service record, is a DNS entry that is used to outline the servers which run a specific service for a domain name. Quite simply, you will be able to use your Internet domain not just for a website, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for instance, while you still have an Internet site with it. Whenever you create the SRV record, you may choose what IP it is going to employ, on which port the connection to the particular server will be established as well as the priority and the weight of the record assuming that there are several SRV records for the exact same service. The latter option allows you to use different machines for load balancing and redundancy. With this kind of DNS records, you can use the same domain name many different purposes and even with different providers in case the same one is unable to provide all services you need.
