DNS is a great technology that everyone uses over internet. How would you reach a given website if you weren’t able to solve its name to the IP address? Would you memorize the public IP addresses of any website you want to reach? No, and with IPv6 coming in the future, DNS will become even more important for internet consumption. But DNS has one drawback: its records are usually static, and if a platform is dynamic and spawn/removes instances on the fly, it needs to have a way to modify the DNS records that are published, so that a non-reachable instances is not even listed.

This limit is designed to preserve the availability of the management interface, but still there are situations where this limit is a problem, and you would like to increase it. Hopefully, there’s a solution.
