DHCP client disclosing less identifying information.

dhcpcanon - DHCP anonymity profile

DHCP client disclosing less identifying information.

Python implmentation of the DHCP Anonymity Profile (RFC7844) designed for users that wish to remain anonymous to the visited network minimizing disclosure of identifying information.

Technologies

This implementation uses the Python Scapy Automata

What is the Anonymity Profile?

As the RFC7844 stats:

Some DHCP options carry unique identifiers. These identifiers can enable device tracking even if the device administrator takes care of randomizing other potential identifications like link-layer addresses or IPv6 addresses. The anonymity profiles are designed for clients that wish to remain anonymous to the visited network. The profiles provide guidelines on the composition of DHCP or DHCPv6 messages, designed to minimize disclosure of identifying information.

What is DHCP?

From Wikipedia:

The Dynamic Host Configuration Protocol (DHCP) is a standardized network protocol used on Internet Protocol (IP) networks. The DHCP is controlled by a DHCP server that dynamically distributes network configuration parameters, such as IP addresses, for interfaces and services. A router or a residential gateway can be enabled to act as a DHCP server. A DHCP server enables computers to request IP addresses and networking parameters automatically, reducing the need for a network administrator or a user to configure these settings manually. In the absence of a DHCP server, each computer or other device (eg., a printer) on the network needs to be statically (ie., manually) assigned to an IP address.
