DoH-Gen-C-AABBCC

Dataset of DNS over HTTPS traffic (AdGuard, AhaDNS, BlahDNS, BraveDNS, Comcast, CZNIC)

The dataset contains DoH and HTTPS traffic that was captured in controlled environment and generated automatically by Chrome browser with enabled DoH towards 6 different DoH servers (AdGuard, AhaDNS, BlahDNS, BraveDNS, Comcast, CZNIC) and a web page loads towards a sample of web pages taken from Majestic Million dataset. The data are provided in the form of PCAP files. However, we also provided TLS enriched flow data that are generated with opensource ipfixprobe flow exporter. Other than TLS related information is not relevant since the dataset comprises only encrypted TLS traffic. The TLS enriched flow data are provided in the form of CSV files with the following columns:

Column Name
Column Description

DST_IP
Destination IP address

SRC_IP
Source IP address

BYTES
The number of transmitted bytes from Source to Destination

BYTES_REV
The number of transmitted bytes from Destination to Source

TIME_FIRST
Timestamp of the first packet in the flow in format YYYY-MM-DDTHH-MM-SS

TIME_LAST
Timestamp of the last packet in the flow in format YYYY-MM-DDTHH-MM-SS

PACKETS
The number of packets transmitted from Source to Destination

PACKETS_REV
The number of packets transmitted from Destination to Source

DST_PORT
Destination port

SRC_PORT
Source port

PROTOCOL
The number of transport protocol

TCP_FLAGS
Logic OR across all TCP flags in the packets transmitted from Source to Destination

TCP_FLAGS_REV
Logic OR across all TCP flags in the packets transmitted from Destination to Source

TLS_ALPN
The Value of Application Protocol Negotiation Extension sent from Server

TLS_JA3
The JA3 fingerprint

TLS_SNI
The value of Server Name Indication Extension sent by Client

The DoH resolvers in the dataset can be identified by IP addresses written in doh_resolver_ip.csv file.

The main part of the dataset is located in DoH-Gen-C-AABBCC.tar.gz and has the following structure:
