How this service works
MX 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 MX records (mail exchanger hostnames and priorities), TTL, DNS response code (NOERROR, NXDOMAIN, or SERVFAIL), whether the AliDNS resolver validated DNSSEC for the response, and the resolver's answer latency in milliseconds.
Example use cases
Email deliverability troubleshooting via AliDNS
“Can you check what MX records AliDNS is returning for mailchimp.com? I want to see the mail servers, the TTL, and whether the response is NOERROR or something else.”
Comparing resolver answers for split-horizon detection
“I suspect AliDNS might be returning different MX records for company.com than other resolvers. Can you look up the MX records for company.com specifically via AliDNS so I can compare them?”
Verifying DNS propagation of new MX records
“We just updated MX records for ourdomain.com — can you check if AliDNS at 223.5.5.5 has picked up the new records yet, and tell me the TTL and response code?”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/mx/via/alidns?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to see how AliDNS (Alibaba's public resolver at 223.5.5.5) answers MX queries — for example when investigating DNS propagation in China-adjacent networks, detecting split-horizon configurations, or comparing resolver-specific filtering behavior against other resolvers like Cloudflare or Google.
Side effects
- NXDOMAIN returned when the domain does not exist
- SERVFAIL returned when AliDNS cannot resolve the domain
- Empty MX record set for domains with no mail exchangers configured
- Network timeout if AliDNS is unreachable
- Invalid or malformed domain name input returns an error
