An SRV record, which means Service record, is a DNS entry that is used to identify the servers that run a certain service for a domain name. In other words, you will be able to use your domain name not only for an Internet site, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, for example, while you still have a website with it. When you create the SRV record, you may choose what IP it is going to employ, on which port the connection to the particular server will be established in addition to the priority and the weight of the record assuming that there are 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 type of DNS records, you may use the same domain for a number of purposes and even with different providers in case the same one is not able to provide all services that you need.
