An SRV record, which stands for Service record, is a DNS entry that is used to outline the servers that run a certain service for a domain. Basically, you’ll 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, for instance, while you still have an Internet site with it. When you set up the SRV record, you can choose what Internet Protocol it will employ, on which port the connection to the particular server will be established along with the priority and the weight of the record in case that you have a number of SRV records for the exact same service. The second option will permit you to employ different machines for load balancing and redundancy. Using this type of DNS records, you could use the same domain address for a variety of purposes and even with different companies if the same one can't provide all services you need.
