DNS Lookup
Live DNS record checks for infrastructure, email authentication, and domain health investigations.
Use this DNS Lookup tool to inspect authoritative and recursive DNS signals in one run. It surfaces address records, name servers, email routing records, and TXT policy records used by SPF, DKIM, and DMARC.
This is designed for incident response, domain migrations, and deliverability audits where you need raw DNS outputs quickly without opinionated scoring layers.
