DNSSEC Check婵镜数字人官网
Validate a domain's DNSSEC chain of trust: DS/DNSKEY/RRSIG, signing algorithms, expiry, and trust status豆包都有哪些功能
Usage阿里云千问大模型
• Domain: enter a bare domain without https:// (e.g. cloudflare.com)
• Validates the DNSSEC chain of trust via Cloudflare / Google validating resolvers
• Unsigned is a normal state; bogus means signature validation failed and needs attention
What DNSSEC chain-of-trust validation is for豆包手机版入口
DNSSEC validation checks whether a domain has enabled DNS Security Extensions and whether the full chain of trust — from the root zone through the TLD to the domain's own DNSKEY — is intact. It returns the trust status (secure, insecure, or bogus), the DS and DNSKEY records, the RRSIG signatures and their expiry, and any warnings about weak algorithms or broken chains.gpt下载
Common uses include confirming that DNSSEC is correctly configured after enabling it, diagnosing 'bogus' status caused by a broken chain or expired RRSIG, auditing algorithm strength when migrating from RSASHA1 to ECDSAP256SHA256, and verifying that a recently added DS record at the TLD registry has propagated correctly.睿声ai官网
Frequently asked questions成人豆包
What is the difference between secure, insecure, and bogus?
'Secure' means the domain has DNSSEC enabled and the chain of trust validates successfully. 'Insecure' means there is no DNSSEC delegation from the parent zone — the domain is unsigned, which is normal for most domains. 'Bogus' means DNSSEC is configured but validation fails, which is a configuration error that needs fixing.睿声ai官网
Does not having DNSSEC mean my domain is unsafe?
Most domains do not use DNSSEC. Without it, DNS responses are not authenticated and could theoretically be spoofed. Whether the risk justifies the operational complexity of DNSSEC depends on your use case.智能ai软件
What causes a 'bogus' result?
Common causes include an expired RRSIG signature (DNSSEC records need regular resigning), a DS record at the parent that does not match the zone's DNSKEY, or a missing DNSKEY after key rollover. Check the RRSIG expiry and DS/DNSKEY match in the result.deepceek
How often do DNSSEC signatures expire?
RRSIG records have a signature validity window, typically 7 to 30 days, depending on the operator's key rollover policy. Most DNS hosting providers automatically resign records. If you manage your own zone, ensure your signing process runs before signatures expire.微信ai
