An SRV record, which stands for Service record, is a DNS entry which is used to define the servers that run a specific service for a domain name. Quite simply, you’ll be able to use your domain not only for a website, but also for an instant messaging server, a video streaming host or even 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 use, on which port the connection to the particular server will be established along with the priority and the weight of the record assuming that there are several SRV records for the very same service. The latter option allows you to employ different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain name many different purposes and even with different companies in case the same one is not able to provide all services you need.
