DNS Servers

United States of America 4329 local DNS servers

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.
