An SRV record, which stands for Service record, is a DNS entry employed to define the servers that run a certain service for a domain. In other words, you will be able to use your domain not only 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 an Internet site with it. When you set up the SRV record, you may choose what IP it will use, on which port the connection to the particular server will be established plus the priority and the weight of the record in case that you have a number of SRV records for the exact same service. The second option allows you to employ different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain address 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.
