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 consists of monitoring one of your servers for availability and automatically changing the DNS settings when it detects that it is not responding properly.
dns failover a record
There are many different ways you can use DNS for failover. Some methods use round-robin, i.e. publishing multiple IP addresses and removing them when they are found to be down, while others combine some level of monitoring with this process.
DNS round robin is very simple, and can work well for smaller sites, where the load is low and the site doesn't require much redundancy. However, it does have some issues and you need to be very careful in how you set your TTL. The problem with this approach is that when you publish a dead address, a certain percentage of your users will still be connecting to the dead server until the TTL expires.
To prevent this from happening, you need to have a solid understanding of DNS resolvers and how they work. You should also be able to use the DNS recursive methods that are available in most failover tools.
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. In your failover configuration, you must specify domain names and host names for each record. You can also use a host:port pair list or a DNS A record name that represents multiple IP addresses for this.
dns record multiple a failover
DNS multiple records failover is similar to DNS round robin except that each record contains multiple IPs. This makes it much easier to setup a failover because DNS resolvers can change the DNS settings for a failed IP address when they are aware of a backup.
In addition to monitoring internal IP addresses, dns failure requires external monitoring. This type of monitoring is not a part of the default DNS configuration, but it can be added by configuring the health checks module in your DNS account.
High availability dns failure
To achieve high availability, you should ensure that your DNS IP address can be reached from the Internet. This is very important, because it ensures the majority of site visitors will have access to it even if 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 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.
