An SRV record, which signifies 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 just for an Internet 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 website with it. When you create the SRV record, you can choose what Internet Protocol it'll use, on which port the connection to the specific server is going to be established along with the priority and the weight of the record assuming that you have a number of SRV records for the very same service. The second option will allow you to employ different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain address for a number of purposes and even with different companies if the same one cannot provide all services that you need.
