An SRV record, which is short for Service record, is a DNS entry which is used to identify the servers that run a particular service for a domain name. Basically, you are able to use your Internet domain not just for a website, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for example, while you still have an Internet site with it. If you set up the SRV record, you can select what Internet Protocol it'll use, on which port the connection to the specific server will be established along with the priority and the weight of the record in case that there are several SRV records for the very same service. The latter option allows you to use different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain name for a number of purposes and even with different providers if the same one is unable to provide all services that you need.
