Failover DNS automates the DNS failover process to ensure that your website and network services remain up and operational in case of server failure. It works by monitoring the availability of one of your server and changing the DNS settings if that server does not respond properly.
dns failover a record
There are different ways of using DNS to failover. Some use the round-robin technique, i.e. Several IP addresses are published and removed when the IP address is down.
DNS round robin can be very simple. It works best for small sites with low traffic and little redundancy. TTL settings are important and should be done carefully. This approach has the problem that a certain percentage will continue to connect to the dead address until the TTL expires.
To prevent this from happening, you need to have a solid understanding of DNS resolvers and how they work. It is also important to understand the different DNS recursive algorithims offered by most failover programs.
dns failover configuration
For failover to work, you need two DNS records: one for your primary server, and the other for the backup. You must specify the domain and host names that correspond to each of these records in your failover configuration. For this, you can use a host-port pair list or DNS A record names that represent multiple IP addresses.
Multiple a record failover dns
DNS multiple a record failover is exactly the same as DNS Round Robin, except with multiple IPs in each record. The DNS resolvers will be more willing to make changes to the DNS settings when they know a back up is available.
In order to ensure a successful dns switchover, the system will need to monitor the IP of the failed address in addition. This type monitoring isn't part of the standard DNS configuration. It can be added to the DNS account by configuring the Health Checks module.
High availability dns failover
To achieve high availability, you should ensure that your DNS IP address can be reached from the Internet. This is a crucial step as it ensures that most of your website visitors can access it, even if you lose the primary server.
You can do this by adding DNS records that contain a secondary IP, or use a server that automatically updates the DNS records when it determines that the primary IP is no longer reachable. The system performs this task by monitoring a set of IP addresses. It then makes the necessary change once it has determined that the primary URL is no more reachable.
