What are the Suggestions to overcome DNS disadvantages?

To overcome DNS disadvantages, organizations can implement DNS redundancy by using multiple DNS servers to enhance reliability and availability. Employing DNSSEC (Domain Name System Security Extensions) can help protect against certain types of attacks like cache poisoning. Additionally, utilizing a content delivery network (CDN) can improve DNS resolution times and distribute traffic more efficiently, while regular monitoring and updates of DNS configurations can mitigate vulnerabilities.
