Look up A, AAAA, TXT, MX, NS, and more for any domain. Useful for SPF, DKIM, mail, and hosting verification before go-live.
No records returned for this query. The name may not exist for this type, or DNS has not propagated yet.
TXT — SPF (v=spf1), domain verification, and DKIM-related records. MX — which mail servers receive email for the domain. A / AAAA — where website traffic should land. NS — authoritative nameservers. Run a lookup after every DNS change at your registrar or CDN.
A mistyped MX or missing SPF record can break mail delivery or mark legitimate traffic as spam. Hosting and proxy teams often verify DNS first because application errors are easier to debug when name resolution is already correct. This tool gives a quick live view without installing CLI tools.
SPF lives in TXT records starting with v=spf1. It tells receiving mail servers which IPs may send mail for your domain. Google, Microsoft, and Zoho verification also use TXT. Select TXT on your apex domain (e.g. example.com) to confirm what is published publicly.
Wrong hostname (checking www when records are on the apex), wrong record type, propagation delay after edits, or DNS only on a subdomain. If you expect mail records, query the same hostname your MX provider documents — not always the bare domain.
Enter a hostname, pick a record type, and click Check DNS. Results list each value with TTL when available. Re-run after you save changes at Cloudflare, Namecheap, GoDaddy, or your DNS host until the new values appear.
Developers confirming API and app domain records before release.
Marketers and founders verifying SPF before cold email or newsletters.
DevOps teams auditing MX/NS after migrations or CDN cutovers.
Proxy users checking target domains resolve correctly before automation jobs.
Once domains resolve correctly, route automation through Chilly Proxy residential, premium geo, and IPv6 plans. Stable exit IPs and clean routing help scraping, account workflows, and geo tests succeed with fewer retries.

What is an SPF record?
SPF is a TXT record (usually v=spf1 ...) that lists which mail servers may send email for your domain. It helps receivers reject spoofed mail.
How do I check SPF for my domain?
Choose record type TXT, enter your domain (e.g. yourbrand.com), and run the check. Look for a value starting with v=spf1.
Why do A and AAAA return different hosts?
Many sites publish only A (IPv4) or both A and AAAA (dual-stack). Missing AAAA does not always mean the site is down — use the IPv6 checker for full dual-stack review.
How long until DNS changes show up?
TTL controls cache time. Low TTL (300s) can update in minutes; high TTL may take hours. Re-run this tool after each change to confirm propagation.
Do you store domains I look up?
No account is required. Lookups are for quick diagnostics; run checks as often as you need while configuring DNS.
Can I check subdomains?
Yes. Enter any hostname — e.g. mail.example.com for MX-related hosts or _dmarc.example.com for DMARC TXT if published there.
