Solution for the problem is provided below, please comment if any doubts:

The three DNS servers that compares here are:

• Comcast DNS (A home ISP)
• Google DNS
• openDNS

The home ISPs has their own DNS server but it will provide only limited services to the users. The domain-IP mappings in the home ISP will be less. So the home ISP DNS server may need to use other global DNS servers for their proper functioning.

The Google DNS server is one which is most popularly used one. It has higher reliability and a favorable feature makes it a hot choice for the web resource seekers.

The openDNS is another important DNS server used by many ISPs. Most of the ISPs use openDNS if their own DNS server fails to find the result.

Cost:

The home ISP DNS server cost will be hidden under the service cost, the DNS service is also comes under the internet package, so it is difficult to distinguish it, but surely it comes with a cost. The openDNS comes with basic features free, but the premium features comes at a cost around $50 to around $1000.

Speed:

• The home ISP is most speed in most of the cases if we uses only common websites, for extended services and complex quires home ISP can’t perform better. The Google DNS is having best capability but over using make it slow. The openDNS with premium registration gives the best performance in terms of speed.

Security:

• The home ISP DNS Comcast DNS has only nominal security features, it uses the other company security features to give security for the network. The Google DNS provide many unique security features. But the openDNS provided the best security with premium registration.

Usability:

For business purpose the openDNS DNS service will works better since it provide many unique features that is useful with the business purpose.
