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 can use your Internet domain not just for an Internet site, 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 may choose what Internet Protocol it is going to employ, on which port the connection to the particular server will be established plus the priority and the weight of the record provided that you have a number of SRV records for the exact same service. The latter option will permit you to use different machines for load balancing and redundancy. With this kind of DNS records, you could use the same domain address for a number of purposes and even with different companies if the same one is unable to provide all services that you need.
