Round Robin Configuration of Records

What are Round Robin Records?

Load balancing, also known as a Round Robin configuration, allows you to distribute traffic loads evenly among multiple servers. Simply create multiple records with the same name, but with different associated IP’s/hostnames/target servers. If you want to create Round Robin but with the traffic load distributed unevenly, refer to the Weighted Round Robin tutorial.

For this tutorial, we will be demonstrating how to create a Round Robin configuration using A records. You can apply the same steps and principles to all other record types. Round robin records can be configured for A, AAAA, MX, NS, PTR, SRV, or TXT records.

You can also configure Round Robin with DNS Failover, learn how in this tutorial.

4. In this screen, you will add the record information. Follow the steps below:

A) Name: This will be the hostname for your record. It is important to note, the domain name is automatically appended to the “Name” field of the record.
B) TTL: Edit the TTL. Time to Live is measured in seconds and is the amount of time the record will cache in resolving name servers and web browsers.
C) Record Mode: The Record Mode will be left at Standard for this tutorial. Please note, the other Record Mode options are covered in different tutorials.
D) IP Address: The IPv4 address of your FQDN. An IP (Internet Protocol) address consists of a four octet 32-bit address.
E) Add Another IP: Click the Add Another IP button. You can add as many IP’s as you want to this record.

5. Enter a second IP address for the A record to point to. Traffic will be split evenly between both hosts. You can click the slider to disable one of the records at any time. Click Save and Close.
