An SRV record, which is short for Service record, is a DNS entry that is used to define the servers that run a certain service for a domain. Put simply, you’ll be able to use your Internet domain not just for a website, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have a site with it. When you set up the SRV record, you may choose what IP it will employ, on which port the connection to the specific server is going to be established along with the priority and the weight of the record in case that you have several SRV records for the exact same service. The latter option allows you to employ different machines for load balancing and redundancy. Using this type of DNS records, you could use the same domain for a number of purposes and even with different providers in case the same one is unable to provide all services you need.
