An SRV record, which signifies Service record, is a DNS entry employed to outline the servers which run a particular service for a domain. Quite simply, you will be able to use your domain name not just for an Internet 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 an Internet site with it. When you set up the SRV record, you can pick what Internet Protocol it's going to employ, on which port the connection to the specific server will be established plus the priority and the weight of the record assuming that you have several SRV records for the very same service. The latter option will permit you to employ different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain address many different purposes and even with different companies if the same one is unable to provide all services you need.
