An SRV record, which stands for Service record, is a DNS entry that is used to define the servers that run a specific service for a domain name. In other words, you can 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, as an example, while you still have an Internet site with it. If you create the SRV record, you may choose what Internet Protocol it is going to 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 several SRV records for the exact 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 providers in case the same one cannot provide all services you require.
