DNS Lookup & DNS Checker – All Records & Reverse DNS

Look up the DNS of one domain or 50,000 at once. Paste domains, subdomains, website URLs, email addresses or IP addresses, and for each one you get:

• All common records: A (IPv4), AAAA (IPv6), CNAME, MX, NS, TXT, SOA and CAA.
• Reverse DNS (PTR) for the domain's IPs. Paste an IP address on its own to get its reverse DNS.
• DNS host from the name servers (Cloudflare, Route 53, GoDaddy, Namecheap, Azure, Akamai, Wix, Shopify and many more), and the mail provider from the MX records (Google Workspace, Microsoft 365, Zoho, Proofpoint ...).
• A three-resolver check: Cloudflare, Google and AliDNS (Asia) are asked for the IPv4 addresses, and resolvers_agree tells you if they match. Useful after moving a site or changing name servers.
• A one-line summary in plain words.

Built for website and server migrations, lead lists (which host and mail provider a company uses), security reviews, domain portfolios and IT inventories.

Example output row

How to use

1. Click Try for free (or Start) at the top of this page to open the input form.
2. Fill in Domains or IP addresses. Up to 50,000 domains, subdomains, website URLs, email addresses or IP addresses. The form comes with a working example, so you can also run it as it is.
3. Click Start and wait for the run to finish.
4. Download the results as Excel, CSV or JSON from the Output tab, or get them through the Apify API, a schedule or an integration (Make, Zapier, Google Sheets ...).

Pricing

Pay per event, no subscription:

• $0.0005 per domain or IP looked up ($0.50 per 1,000).
• $0.001 per run start.

A domain that does not exist is still a result. Lookups the DNS does not answer, and text that is not a domain or IP, are free. Works on the free Apify plan.

Input

Field	What it does
domains	Domains, subdomains, URLs, email addresses or IPs (IPv4 and IPv6), up to 50,000. info@shop.com looks up shop.com; duplicates are looked up once.

Good to know

• Lookups go through public DNS-over-HTTPS (Cloudflare, with Google as fallback), so you see what the internet sees, not a cached local answer.
• Different IPs from the three resolvers are normal for sites behind a CDN or geo DNS, which hand out the nearest server. For a plain site it usually means a change that has not reached every resolver yet.
• A subdomain such as www.example.com has no name servers of its own, so ns is empty there; look up example.com for them.
