Failover DNS, also known as DNS failover, is a process for automating DNS failover. It can be used in order to keep your network or website up and running if a server fails. It involves monitoring your server for availability, and changing DNS settings automatically if it detects that the server is not responding.
A record-breaking dns switchover
There are many different ways you can 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.
The DNS round-robin system is simple and works well for smaller websites where load is low, and redundancy isn't needed. It does have its issues, and you must be careful when setting your TTL. This approach has the problem that a certain percentage will continue to connect to the dead address until the TTL expires.
To avoid this, it is important to understand how DNS resolvers operate and how you can configure them. It is also important to understand the different DNS recursive algorithims offered by most failover programs.
dns failover configuration
To set up failover using DNS, you must create two separate DNS records, one for the primary and another for the backup server or 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.
Dns failover multiple a records
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.
Dns failover is not possible without some external monitoring of the failed IP address. This monitoring must be done in addition to the internal monitoring the failover system performs on the backup IP. 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
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 a very important step to take, as it will ensure that the majority of your site visitors will be able to access it even if the primary server fails.
This can be done by adding a DNS entry that includes a secondary address, or using a webserver that changes DNS records for all incoming requests when the primary address becomes unreachable. The system does this by monitoring a specified range of IP addresses and making the change when it determines that the primary IP address is no longer reachable.
