An SRV record, which means Service record, is a DNS entry which is used to outline the servers which run a specific service for a domain name. In other words, you’ll be able to use your domain not just for an Internet 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 site with it. Whenever you set up the SRV record, you can pick what Internet Protocol it's going to use, on which port the connection to the specific server is going to be established in addition to the priority and the weight of the record in case that you have a number of SRV records for the very same service. The latter option will allow you to employ different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain address many different purposes and even with different companies if the same one is unable to provide all services you require.
