An SRV record, which means Service record, is a DNS entry employed to identify the servers that run a particular service for a domain. Put simply, you’re able to use your domain name 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 site with it. When you create the SRV record, you can choose what Internet Protocol it'll use, on which port the connection to the particular server will be established in addition to the priority and the weight of the record in case that there are several SRV records for the very same service. The latter option will allow you to employ different machines for load balancing and redundancy. Using this type of DNS records, you could use the same domain for various purposes and even with different companies in case the same one is unable to provide all services you require.
