What is DNSFetch?

DNSFetch is a free online DNS lookup tool that helps website owners, developers, and email administrators inspect the DNS records of any domain in seconds. Whether you are troubleshooting a mail delivery issue, migrating a website to a new host, verifying that a nameserver change has propagated, or auditing the security posture of a domain, DNSFetch gives you a clean, ad-lite view of the same information your resolver sees.

Enter a domain name, choose the record type you want to inspect, and DNSFetch will query authoritative DNS data and display the answer — complete with the record host, TTL, and value. No account, no software install, and no daily quota. Every query runs server-side, so results reflect the real state of DNS and are not affected by your browser cache.

Why Choose DNSFetch?

Common DNS Record Types

A Record: Maps a hostname to an IPv4 address. This is the record most people think of as “pointing” a domain at a server.

AAAA Record: The IPv6 equivalent of an A record. Required for domains that need to be reachable over IPv6.

MX Record: Defines the mail servers responsible for accepting email for a domain, along with a priority value.

TXT Record: Stores arbitrary text data, most commonly used for domain ownership verification, SPF, DKIM, and DMARC policies.

NS Record: Declares the authoritative nameservers for a zone. If these are wrong, nothing else in DNS will resolve correctly.

CNAME Record: An alias that points one hostname at another. Useful for pointing subdomains at third-party services.

Frequently Asked Questions

How long does DNS propagation take?

DNS propagation is really just cache expiration. Most resolvers respect the TTL published on the record, but many intermediate caches round up. In practice, expect changes to be visible worldwide within a few hours, and complete within 24 to 48 hours.

Why is my DNS record not updating?

The most common cause is a resolver still serving a cached copy of the old record. Try querying from a different network, use a public resolver such as 1.1.1.1 or 8.8.8.8, or lower the record TTL a day before you plan to change it.

Is this DNS checker really free?

Yes. DNSFetch is free to use with no registration. We apply a light rate limit per IP address to keep the service fair and available for everyone.

Do you store the domains I look up?

We keep short-lived query caches (a few minutes) to speed up repeat lookups, and standard web server logs. We do not build a public database of the domains people search. See our Privacy Policy for details.
