Summary

Application that is able to sniff dhcp packets and generate network prefixes usage statistics.

Building and running the application

To build the application open terminal in this folder and run:

$ make

Make command will compile the program through g++ compiler, then you can run application by running:

$ ./dhcp-stats [-r filename] [-i interface-name] ip-prefix [ip-prefix [ ... ]]

• -r filename: specifies file for analyzing dhcp packets
• -i interface-name: specifies interface for analyzing dhcp packets
• ip-prefix: IPv4 prefixes from which the program will generate statics (xxx.xxx.xxx.xxx/xx)

Constraints: There should be passed parameter -r or -i but not both together.

Example run:

$ ./dhcp-stats -i eth0 192.168.1.0/24 192.168.0.0/22 172.16.32.0/24

Example output:

$ IP-Prefix Max-hosts Allocated addresses Utilization
192.168.1.0/24 254 65 25.59%
192.168.0.0/22 1022 203 19.86%
172.16.32.0/24 254 30 11.81%
