An SRV record, which signifies Service record, is a DNS entry which is used to identify the servers which run a particular service for a domain name. In other words, 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 a Voice-Over-IP server, for 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 use, on which port the connection to the specific server is going to be established plus the priority and the weight of the record provided that you have a number of SRV records for the very same service. The latter option will enable you to employ different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain many different purposes and even with different companies in case the same one cannot provide all services that you need.
