An SRV record, which stands for Service record, is a DNS entry that is used to outline the servers which run a specific service for a domain. Quite simply, you’re able to use your domain name not only for a web 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 is going to be established plus the priority and the weight of the record provided that there are several SRV records for the exact same service. The latter option allows you to use different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain address many different purposes and even with different providers in case the same one can't provide all services you require.
