Creating SRV records .

Service (SRV) records are a way of defining a server, or group of servers that are responsible for a specific service. SRV records  can be considered as all-purpose MX records in the way that you can set the service to use multiple servers, and set a priority for each server in your list. SRV records, however, also have a "weight" value that you can assign, allowing you to spread a proportion of requests across each of your servers. This would allow a slower computer to take a smaller amount of the traffic if needed, allowing for greater efficiency across your network.
