The simulation has following 2 sections:

1. Recursive DNS

• Select a task to begin with.
• Aim is to find the IP Address of a hostname by recursively querying the DNS Servers.
• Begin from the Requesting Host and following proper hierarchy of DNS Servers to find the IP Address.
• Once the IP Address is found, return it back along the same path to the the Requesting Host.
• Keep an eye on the Communication Log to know when IP Address is found.

2. Iterative DNS

• Select a task to begin with.
• Aim is to find the IP Address of a hostname by iteratively querying the DNS Servers.
• Begin from the Requesting Host and following proper hierarchy of DNS Servers to find the IP Address.
• Once the IP Address is found, directly query for the IP Address to reach the hostname server.
• While creating a query:
  • Default hostname is given.
  • Set appropriate value to Type.
  • Enter the IP Address to query for.
  • Submit to send the query.
• Keep an eye on the DNS Reply Messages to know when IP Address is found.
