An SRV record, which signifies Service record, is a DNS entry employed to outline the servers that 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. Whenever you create the SRV record, you can choose what IP it's going to employ, on which port the connection to the specific server is going to be established in addition to the priority and the weight of the record assuming that there are several SRV records for the exact same service. The second option will enable you to use different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain name many different purposes and even with different companies if the same one can't provide all services you require.
