Looking for DNS Contacts

Recent (202002) audits of S&P Global Top 100 Banks and Fortune 500 (US) companies resulted in 4866 domains from 609 companies with failures and 4770 domains and 598 companies with warnings. For more details, see our research and a few examples.

Over the past few months we have attempted contacting various companies' hostmasters to report about significant DNS issues. This includes misconfigured domains that are entirely down and trivial impersonation possibilities. The following is a list of companies we'd like to freely report DNS issues to. Please contact us at contact2020@dnsinstitute.com or @DNSinstitute via Twitter.
