An SRV record, which stands for Service record, is a DNS entry which is used to identify the servers which run a particular service for a domain. In other words, you’re able to use your domain name not just for a site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for instance, while you still have a site with it. When you set up the SRV record, you may choose what Internet Protocol it is going to employ, on which port the connection to the specific server will 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 second option will permit you to use different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain for a number of purposes and even with different companies in case the same one can't provide all services you require.
