What is DNS?

- DNS is a distributed naming system that allows human readable domain names translate in to numeric IP address to function in the world wide web.

Advantages of DNS:

- DNS tree works as a chain of command within the hierarchy (Starting from the root zone followed by the subzones) which allows the queries to be resolve preciesely. - DNS caching reduces traffic load and saves time in future quaries.

- It translates numeric IP addresses in to text (Domain Names) which is user friendly to work in the world wide web.

- DNS are unique.

Disadvantages of DNS:

- DNS queries does not carry client information that triggers name resolution.

- Failure of one of the zonal area might make the DNS hierarchy unstable to retun query.

- Caching can be useless if in future there is a change happenes in the domain.

- Phishing can make the DNS vulnerable which happens to make the graphical user interface almost identical that can make data go to wrong hand and get misused.

- By the enormass growth of internet and web DNS queries might take up more time to answer because of its tree structure mechanism.
