DNSSEC is a security mechanism designed to solve DNS spoofing and cache pollution. The English name is Domain Name System Security Extensions. It uses cryptographic technology to enable the domain name resolution server to verify the responses it receives (including responses for non-existent domain names). ) came from a real server, or was tampered with during transmission.

When it comes to free DNS services, CloudXNS, which has been favored by many webmasters before, should be a good choice. But this all changed in the past few days. Due to some "well-known" reasons, cloudxns suspended parsing for the vast majority of users without any notice. I only discovered this problem after returning from school this week.
