An SRV record, which is short for Service record, is a DNS entry that is used to outline the servers which run a particular service for a domain name. Quite simply, you’re able to use your domain name not only for a website, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for example, while you still have a site with it. Whenever you set up the SRV record, you can choose what IP it will use, on which port the connection to the particular server is going to be established as well as the priority and the weight of the record provided that you have a number of SRV records for the exact same service. The latter option will enable you to use different machines for load balancing and redundancy. With this type of DNS records, you could use the same domain address for various purposes and even with different providers in case the same one cannot provide all services you require.
