An SRV record, which signifies Service record, is a DNS entry that is used to outline the servers which run a specific service for a domain. Basically, you’ll be able to use your Internet domain not only for a site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for example, while you still have a website with it. When you create the SRV record, you can select what Internet Protocol it will employ, on which port the connection to the particular server will be established plus the priority and the weight of the record assuming that you have several SRV records for the exact same service. The second option will permit you to employ different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain name for a variety of purposes and even with different providers in case the same one can't provide all services you require.
