Popular DNS providers like Cloudflare (1.1.1.1), Google DNS address (8.8.8.8), and OpenDNS (208.67.222.222) are known for their high-speed, reliable servers that often outperform the default DNS servers provided by ISPs.
DNS 安全扩展 (DNSSEC) 是为缓解此问题而创建的安全协议。 DNSSEC 通过对数据进行数字签名来防止攻击,以帮助确保其有效性。 为确保进行安全查找,此签名必须在 DNS 查找过程的每个级别进行。 此签名过程类似于人们用笔签署法律文件;此人签署别人无法创建的唯一签名,并且法院专家能够查看该签名并验证文件是否由该人签署的。 这些数字签名可确保数据未被篡改。 DNSSEC 在 DNS 的所有层中实施分层数字签名策略。
Using your ISP's default DNS server has implications for privacy and security. The data in DNS requests isn't encrypted, even if some of the attached metadata is. A man-in-the-middle attack or a nosy employee of your ISP can expose and review your
