DNS (Domain Name System) is the internet phone book. It translates domain names like "example.com" to IP addresses like "93.184.216.34" so your browser knows which server to contact. Without DNS you would have to remember IP addresses for all websites.

How long does DNS propagation take?

DNS propagation typically takes 1-48 hours, depending on the TTL value of the old record. Most changes propagate within 1-4 hours, but in the worst case it can take up to 48 hours before all DNS servers globally have updated.

What is the difference between an A record and CNAME?

An A record points a domain directly to an IP address (e.g. 93.184.216.34). A CNAME record points a domain to another domain (e.g. www.example.com → example.com). CNAME is useful for subdomains and services like Vercel, Netlify and CloudFront.

Why are SPF, DKIM and DMARC important?

These TXT records protect your domain against email spoofing. SPF specifies which servers are allowed to send email from your domain. DKIM cryptographically signs emails. DMARC tells recipients what to do with emails that fail the SPF/DKIM check.

Dns Lookup

What it does

Retrieves DNS records (A, AAAA, MX, CNAME, TXT, NS) for a domain. Useful for troubleshooting and domain verification.

DNS problems are invisible — your website can be down, email can fail, or SSL can be misconfigured without you knowing why

DNS is the internet phone book — it translates domain names to IP addresses. When DNS is misconfigured, your website can be unreachable, emails can disappear, SSL certificates can fail, and domain verification for Google Search Console or other services can fail. The problem is that DNS errors are invisible to regular users — all you see is that "something is not working", without knowing that the cause lies in the DNS configuration.

Website is down but the server works — the cause can be a wrong A record pointing to the wrong IP address, which is impossible to diagnose without DNS lookup
Emails disappear or end up in spam — misconfigured MX records, missing SPF/DKIM/DMARC TXT records are common causes that require DNS inspection to discover
SSL certificates fail during renewal — wrong CNAME records or missing CAA records can prevent automatic certificate renewal without clear error messages
Domain verification for Google, Facebook or other services fails — because the TXT record is not added correctly or has not propagated yet

Complete DNS lookup showing all records for a domain — so you can diagnose problems in seconds

DNS Lookup retrieves all DNS records for a domain instantly — A, AAAA, MX, CNAME, TXT, NS, SOA and CAA. You get a complete overview of the domain DNS configuration presented in a readable format, so you can quickly identify misconfigurations, missing records or propagation issues. Perfect for troubleshooting, domain verification and security checks.

All record types: retrieves A, AAAA, MX, CNAME, TXT, NS, SOA and CAA records in one lookup — so you get a complete overview without doing multiple separate lookups
Readable format: DNS records are presented in a tidy, color-coded overview with explanations — so even non-technical users can understand what they see
Propagation check: see if DNS changes have propagated globally by checking against multiple DNS servers — so you know if your change is active everywhere
Email security: automatically identify SPF, DKIM and DMARC TXT records and get an assessment of email security for the domain

Features

Complete record type support: retrieves A, AAAA, MX, CNAME, TXT, NS, SOA and CAA records — everything you need to diagnose DNS problems and verify configuration
Email security analysis: automatically identifies SPF, DKIM and DMARC records and provides an assessment of whether email security is correctly configured
TTL display: see Time To Live for each record so you know when changes will propagate and how long old records will be cached
History: compare current DNS records with previous lookups to see what has changed — useful for tracking changes and troubleshooting regressions

How it works

Enter the domain name you want to investigate — the tool retrieves all DNS records instantly from authoritative name servers
See all DNS records presented in a tidy overview with record type, value, TTL and explanations — misconfigurations are highlighted automatically
Use the information to diagnose problems, verify domain ownership or check that DNS changes have propagated correctly

Use cases

Web developers troubleshooting website issues who need to verify that A records, CNAME records and NS records point to the correct server and service
IT administrators configuring email security who need to verify that SPF, DKIM and DMARC TXT records are correctly set up to prevent spoofing
SEO specialists verifying domains in Google Search Console who need to confirm that the TXT verification record has been added and has propagated

Why use DNS Lookup?

DNS is the foundation for everything on the internet — websites, email, SSL certificates and domain verification all depend on correct DNS configuration. When something goes wrong, DNS lookup is the first step in troubleshooting, and DNS Lookup makes this instant and clear.

For web developers and IT administrators the tool is a daily work tool. Whether you are migrating a website to a new server, setting up email security or troubleshooting an SSL problem, you need quick access to DNS records without opening the terminal and typing dig/nslookup commands.

The email security analysis is especially valuable. With increasing email spoofing and phishing, correct SPF, DKIM and DMARC configuration is critical. DNS Lookup identifies these records automatically and gives you an assessment of whether email security is sufficient.
