SRV, which is an abbreviation for Service, is a DNS record, which enables you to employ a domain name for a specific service different from an Internet site. By creating a couple of SRV records, you’re able to use the domain with different providers and forward it to numerous servers at the same time, each server managing a separate service. You are able to specify the port number for the connection to every machine, so there will never be any interference. You can even set individual priorities and weight for 2 records which are used for the exact same service, but direct to different servers for redundancy or load balancing. With an SRV record you can employ your domain or a subdomain under it for a Voice-Over-IP server, for instance, and have the actual software running on a number of machines with different providers. Which one a customer of yours will use will depend on the priority and weight values you have set.
