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 monitors one of your servers and changes the DNS settings automatically when it detects it's not responding correctly.
Record dns fails
There are several different ways to use DNS for failover. Some employ a round-robin method, i.e. Many use multiple IP addresses, and remove them if they go down. Others combine this with monitoring.
Round robin DNS is easy to use and is good for smaller sites that don't need much redundancy and have low load. However, it does have some issues and you need to be very careful in how you set your TTL. 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
In order to implement failover via DNS, you will need to create two DNS records. One record for the primary domain and one for a backup domain. Your failover configuration must include the domain names and hostnames that correspond to these records. You can also do this using a host:port-pair list, or DNS A record that represents multiple addresses.
Multiple a record failover dns
DNS multiple records failover is similar to DNS round robin except that each record contains multiple IPs. 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 is monitoring is not part of your default DNS configuration. However, you can configure the health check module to add this monitoring.
High availability DNS failover
The best way for you to achieve high-availability with DNS is by ensuring that your IP addresses are always reachable via the Internet. This is an important step, as you will ensure that your site will still be accessible to the majority of visitors even if your primary server fails.
You can accomplish this by adding a DNS record that contains a secondary IP address in it, or you can use a web server that automatically changes the DNS records of all incoming requests to a specific IP address when it is determined that the primary IP address is no longer accessible. The system monitors a specific range of addresses and makes the change if it finds that the primary IP is no longer accessible.
