The DoH Internet Servers dataset comprises a verified list of Internet servers offering DNS over HTTPS (DoH). 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 April 15th, 2021, and April 23rd, 2021. The dataset contains a total of 234 unique DoH servers, out of which 131 are over IPv4 and 103 over IPv6. The DoH servers belong to 52 unique Autonomous Systems and are associated with a total of 110 unique domain names.
