Dataset to "MUST, SHOULD, DON’T CARE: TCP Conformance in the Wild"

This is the dataset to the research paper "MUST, SHOULD, DON’T CARE: TCP Conformance in the Wild", which was compiled using internet-wide scans to show how Internet hosts and paths conform to basic TCP requirements. Based on this dataset, we uncovered a non-negligible set of hosts and paths that do not adhere to even basic requirements. For example, we observe hosts that do not correctly handle checksums and cases of middlebox interference for TCP options. We identify hosts that drop packets when the urgent pointer is set or simply crash.
