An SRV record, which stands for Service record, is a DNS entry employed to define the servers that run a particular service for a domain. In other words, 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, as an example, while you still have an Internet site with it. Whenever you set up the SRV record, you can pick what Internet Protocol it is going to employ, on which port the connection to the particular server is going to be established as well as the priority and the weight of the record in case that there are several SRV records for the very same service. The second option allows you to use different machines for load balancing and redundancy. Using this kind of DNS records, you could use the same domain address for various purposes and even with different companies in case the same one is unable to provide all services you need.
