An SRV record, which signifies Service record, is a DNS entry that is used to define the servers which run a certain service for a domain name. Quite simply, you’re able to use your domain name not just for a web site, but also for an instant messaging server, a video streaming host or even a Voice-Over-IP server, as an example, while you still have an Internet site with it. When you set up the SRV record, you can pick what IP it will use, on which port the connection to the particular 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 exact same service. The latter option will enable you to employ different machines for load balancing and redundancy. Using this type of DNS records, you can use the same domain name for various purposes and even with different companies if the same one is unable to provide all services you require.
