DNS Backscatter

This web page documents our datasets related to DNS backscatter. DNS Backscatter is all reverse-DNS queries that are sent in reaction to some network-wide event, like scanning or spamming.

Datatset Format

DITL data is network packet captures in pcap format. Data has been host anonymized, where the low-order 8 bits are scrabled with prefix-preserving anonymization.

Getting this data

For ANT-project or PREDICT data see requests.html for details about how to get these datasets.

DITL datasets are also available throuhg DNS-OARC.
