Description

Description

The DoH Internet Servers dataset comprises a verified list of Internet servers offering DNS over HTTPS (DoH). This is an updated 10.17632/ny4m53g6bw.1 The list was created through the aggregation of a previously existing, but incomplete, list of DoH servers. The servers in this dataset went through a verification phase where it was confirmed they were active and working as advertised. The verification was done between May 1st, 2022, and May 4th, 2022. The dataset contains a total of 254 unique DoH servers, out of which 136 are over IPv4 and 118 over IPv6. The DoH servers belong to 59 unique Autonomous Systems and are associated with a total of 106 unique domain names.

The following public lists of existing DoH servers were used to create this dataset:
