An SRV record, which means Service record, is a DNS entry that is used to outline the servers that run a specific service for a domain name. Basically, you’re able to use your Internet domain not only for a site, 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. Whenever you set up the SRV record, you can select what IP it will employ, on which port the connection to the particular server is going to be established in addition to the priority and the weight of the record assuming that you have several SRV records for the exact same service. The second option will allow you to use different machines for load balancing and redundancy. With this type of DNS records, you can use the same domain name for various purposes and even with different companies in case the same one is not able to provide all services you need.
