An SRV record, which is short for Service record, is a DNS entry that is used to define the servers which run a specific service for a domain. Basically, you will be able to use your Internet domain not just for a 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 particular server is going to be established in addition to the priority and the weight of the record in case that there are several 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 for a number of purposes and even with different providers if the same one is not able to provide all services you need.
