An SRV record, which means Service record, is a DNS entry employed to identify the servers that run a certain service for a domain. Put simply, you’ll be able to use your domain name not only for an Internet site, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for instance, while you still have a website with it. If you create the SRV record, you can select what Internet Protocol it will 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 provided that you have several SRV records for the very same service. The second option will enable you to use different machines for load balancing and redundancy. Using this kind 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.
