An SRV record, which stands for Service record, is a DNS entry which is used to identify the servers which run a particular service for a domain. Basically, you are able to use your domain not only for an Internet site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, as an example, while you still have an Internet site with it. When you create the SRV record, you may choose what Internet Protocol it is going to employ, on which port the connection to the specific server is going to be established plus the priority and the weight of the record assuming that you have several SRV records for the very same service. The second option will allow you to use different machines for load balancing and redundancy. Using this kind of DNS records, you can use the same domain name for various purposes and even with different companies in case the same one is unable to provide all services that you need.
