Records returned
- A and AAAA: the IPv4 and IPv6 addresses the domain points to.
- CNAME: when the name is an alias of another host.
- MX: mail servers, with their priority.
- TXT: SPF, DMARC-style policies and verification codes (Google Search Console, Bing and others).
- NS: the name servers that answer for the domain.
Good to know
Answers come from RankCortex's resolver and can be cached for the record's TTL, so a change you just made may take time to show. Lookups for internal names (.local, .internal…) are refused.
Frequently asked questions
Why does my domain have no A record but loads fine?
Check the www version: many sites only set records on www and redirect the bare domain elsewhere, or use a CNAME flattening feature of their DNS host.
Can I have two SPF records?
No. A domain must have one SPF TXT record; with two, SPF checks fail. Merge them into one.
