An SRV record, which means Service record, is a DNS entry which is used to outline the servers which run a certain service for a domain. In other words, you are able to use your Internet domain not only for a web 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. Whenever you set up the SRV record, you can pick what Internet Protocol it is 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 very same service. The latter option will allow you to use different machines for load balancing and redundancy. Using this kind of DNS records, you could use the same domain name for a variety of purposes and even with different companies if the same one cannot provide all services you require.
