How this service works
CAA records for a domain as answered by AliDNS 223.5.5.5 (DNS over HTTPS): the records, TTL, response code (NOERROR/NXDOMAIN/SERVFAIL), whether the resolver validated DNSSEC, and the resolver's answer time. Compare resolvers to spot propagation lag, filtering or split-horizon answers. $0.01 per lookup.
Output
Returns the CAA records for the queried domain as seen by AliDNS 223.5.5.5, including: the record values (issuer tags and domain names), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the resolver performed DNSSEC validation, and the resolver's answer latency in milliseconds.
Example use cases
Detect CAA propagation lag via AliDNS
“I just updated the CAA records for mycompany.com — can you check what AliDNS is returning right now so I can compare it against what Cloudflare and Google see and spot any propagation delay?”
Audit authorized CAs from Chinese resolver
“What CAA records does AliDNS return for shopify.com? I want to know which certificate authorities are authorized and whether DNSSEC validation passed on that resolver.”
Investigate split-horizon CAA discrepancy
“I think AliDNS might be giving different CAA answers for tesla.com than other resolvers — can you pull the CAA records from AliDNS including the response code and answer time so I can investigate?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/caa/via/alidns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to see how AliDNS (a major Chinese public resolver) answers CAA queries — particularly useful for comparing resolver behavior across geographies, detecting propagation lag, identifying filtering or split-horizon DNS setups, or auditing certificate authority authorization from the perspective of users in China or regions served by AliDNS.
Side effects
- Domain does not exist — returns NXDOMAIN response code
- AliDNS resolver is unreachable or times out — returns SERVFAIL
- Domain has no CAA records — returns NOERROR with empty answer section
- Invalid domain name format — likely returns an error or SERVFAIL
- Payment not processed — request rejected before DNS query is made
