An SRV record, which means Service record, is a DNS entry employed to identify the servers that run a particular service for a domain. Basically, you’re able to use your Internet domain not only for an Internet site, 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. If you set up the SRV record, you may choose what IP it's going to use, on which port the connection to the particular server will be established plus the priority and the weight of the record in case that you have a number of SRV records for the very same service. The latter option will permit you to employ different machines for load balancing and redundancy. Using this kind of DNS records, you could use the same domain name many different purposes and even with different companies if the same one can't provide all services you require.
