Are the claims of providing improved security valid?How do they compare with your ISP’s DNS service?

Domain Name Service

Many organizations offer a free domain name resolution service that resolves DNS requests through a worldwide network of redundant DNS servers. The claim is that this is faster and more reliable than using the DNS servers provided by Internet service providers (ISPs). These DNS servers are supposed to improve security by maintaining a real-time blacklist of harmful websites and warning users when they attempt to access a site containing potentially threatening content. The providers also say that using their services can reduce exposure to types of DNS poisoning attacks. Research free DNS services. Identify at least three providers and create a table comparing their features. Are the claims of providing improved security valid?How do they compare with your ISP’s DNS service?
