An SRV record, which stands for Service record, is a DNS entry that is used to identify the servers which run a specific service for a domain name. Basically, you are able to use your Internet domain not just for a website, but also for an instant messaging server, a video streaming host or perhaps a Voice-Over-IP server, for example, while you still have a website with it. Whenever 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 assuming that you have a number of SRV records for the very same service. The latter option allows you to use different machines for load balancing and redundancy. Using this type of DNS records, you may use the same domain for various purposes and even with different companies in case the same one is unable to provide all services you need.
