An SRV record, which stands for Service record, is a DNS entry that is used to define the servers which run a particular service for a domain name. Put 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 even a Voice-Over-IP server, as an example, while you still have a website with it. Whenever you create the SRV record, you can choose what IP it'll employ, on which port the connection to the particular server is going to be established in addition to the priority and the weight of the record in case that you have several SRV records for the exact same service. The latter option will permit you to employ different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain address for various purposes and even with different companies if the same one cannot provide all services you require.
