title: DoH-Gen-C-AABBCC

description: 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 <strong><em>doh_resolver_ip.csv </em></strong>file. The main part of the dataset is located in <strong><em>DoH-Gen-C-AABBCC.tar.gz </em></strong>and has the following structure: <pre><code>. └─── data | - Main directory with data └── generated | - Directory with generated captures ├── pcap | - Generated PCAPs │ └── chrome └── tls-flow-csv | - Generated CSV flow data └── chrome</code></pre> <strong>Total stats of generated data:</strong> Name Value Total Data Size 39.9 GB Total files 12 DoH extracted tls flows ~35 K Non-DoH extracted tls flows ~247 K <strong>DoH Server information</strong> Name Provider DoH query url AdGuard https://adguard-dns.com https://dns.adguard.com/dns-query AhaDNS https://ahadns.com https://doh.it.ahadns.net/dns-query BlahDNS https://blahdns.com https://doh-de.blahdns.com/dns-query BraveDNS https://brave.com https://basic.bravedns.com Comcast https://corporate.comcast.com https://doh.xfinity.com/dns-query CZNIC https://www.nic.cz https://odvr.nic.cz/doh
