An SRV record, which means Service record, is a DNS entry that is used to identify the servers which run a particular service for a domain. In other words, you’ll be able to use your Internet domain not just for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, for instance, while you still have a site with it. Whenever you create the SRV record, you may choose what Internet Protocol it is going to use, on which port the connection to the particular server is going to be established along with the priority and the weight of the record provided that there are several SRV records for the exact same service. The second option will enable you to use different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain address for a number of purposes and even with different providers if the same one is unable to provide all services that you need.
