An SRV record, which signifies Service record, is a DNS entry employed to identify the servers which run a particular service for a domain name. In other words, you are able to use your domain name not only for an Internet site, but also for an instant messaging server, a video streaming host or a Voice-Over-IP server, as an example, while you still have an Internet site with it. When you create the SRV record, you can select what Internet Protocol it's going to use, on which port the connection to the particular server will be established in addition to the priority and the weight of the record provided that there are several SRV records for the exact same service. The latter option will allow you to use different machines for load balancing and redundancy. With this type of DNS records, you may use the same domain name for a variety of purposes and even with different companies in case the same one is not able to provide all services you need.
