For debugging only
This list is intended to help troubleshoot DNS issues. Do not configure these servers as your DNS resolver unless you know and trust the operator. A DNS resolver can log the domains you look up and can manipulate or block DNS responses.
Instead, use your ISP's default DNS server, or a global DNS server operated by an organisation you trust.
