An SRV record, which stands for Service record, is a DNS entry employed to identify the servers which run a certain service for a domain. Quite simply, you are 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, as an example, while you still have a website with it. If you create the SRV record, you may choose what IP it will use, on which port the connection to the specific server is going to be established as well as the priority and the weight of the record in case that there are several SRV records for the exact same service. The latter option will permit you to use different machines for load balancing and redundancy. With this type of DNS records, you could 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 you need.
