What this tool checks.

It pulls DNS records so you can confirm routing, mail, and security in one place.

  • A / AAAA map a host to IPv4 or IPv6.
  • MX names the mail servers and their priority.
  • TXT holds SPF, DKIM, and other policies.
  • CNAME, NS, SOA, SRV, CAA cover aliases, nameservers, and services.

How to read the results.

  • Each record shows a value and TTL.
  • Compare MX priorities so the primary server is first.
  • If a lookup looks off, check the authoritative and truncated flags.

Common questions.

What does a DNS lookup show?
It pulls the records that tell the internet how to route traffic for a domain, including mail and security settings.
Which DNS records should I check first?
Start with A and AAAA for web traffic, MX for mail, and TXT for SPF or DKIM.
How long do DNS changes take to show up?
It depends on TTL. Some changes show in minutes, but caches can keep old values for a few hours.
Why do different tools show different results?
Resolvers cache data and sit in different regions. If results differ, wait for TTL to pass and check again.
