Privacy Policy

Last updated: May 6, 2026

Overview

IPSteak is a free network utility. The home page shows your public IP address and related connection details. The Tools section provides additional lookup utilities for IT and security work, including IP / hostname lookup, DNS records, email authentication, WHOIS / RDAP, threat-feed checks, TLS certificate inspection, subnet math, IPv6 conversion, and MAC vendor lookup. This policy explains what information may be processed when you use the site. It is written as a practical baseline and is not legal advice.

Information processed by the site

When you load IPSteak, your browser necessarily sends technical information such as your IP address, browser user agent, device information, request time, and basic connection metadata. The site uses this information to display your public IP address, browser details, ISP, ASN, and IPv4/IPv6 availability.

When you use a tool in the Tools section, the value you submit (an IP address, domain name, ASN, or MAC address) is sent to one or more third-party network registries or DNS resolvers listed below so the requested lookup can be performed. Submitted values are not stored by IPSteak. The MAC vendor lookup is performed entirely in your browser against a bundled copy of the IEEE OUI registry; the value is not sent to any server.

IPSteak does not ask you to create an account, submit a name, submit an email address, or enter sensitive personal information. Do not submit sensitive personal data (for example, addresses, credentials, or PII) into the lookup tools.

Third-party services

IPSteak relays lookup requests to public network registries, DNS resolvers, and open threat-feed sources. Those providers receive your IP address (because your browser is making the request directly or through a server-side endpoint on this domain) and the value being looked up. The current providers and their privacy notices are:

• Cloudflare (site hosting, 1.1.1.1 DNS-over-HTTPS resolver) — cloudflare.com/privacypolicy, 1.1.1.1 privacy notice
• Google Public DNS (DNS-over-HTTPS fallback resolver) — developers.google.com/speed/public-dns/privacy
• Additional public DoH resolvers (queried in parallel by the DNS propagation tool) — Quad9, AdGuard DNS, DNS.SB, Mullvad DNS, ControlD, Cisco OpenDNS. When you use that tool a server-side endpoint forwards your domain query to each of these resolvers; they may receive the queried domain name and the endpoint's IP address.
• RIPE NCC (RIPEstat ASN, prefix, abuse, geolocation, reverse-DNS data) — ripe.net/about-us/legal/privacy-statement
• ipify (IPv4 / IPv6 detection on the home page) — ipify.org
• rdap.org and the Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC) and domain registrars (WHOIS / RDAP responses) — about.rdap.org
• abuse.ch (FeodoTracker botnet C2 list — used by the blocklist tool) — abuse.ch
• SANS Internet Storm Center / DShield (top-source list — used by the blocklist tool) — dshield.org
• The Tor Project (Tor exit list — used by the blocklist tool) — torproject.org
• IEEE Registration Authority (OUI / MA-L / MA-M / MA-S registry redistributed in /data/oui.json for the MAC lookup tool — bundled and processed in your browser) — standards.ieee.org/products-programs/regauth
• Google (AdSense) — policies.google.com/technologies/partner-sites

For the WHOIS, blocklist, TLS inspector, and DNS propagation tools, requests are handled by server-side endpoints on the ipsteak.com domain. Those endpoints forward WHOIS, blocklist, and DNS propagation queries to the upstream provider (rdap.org, the threat feeds listed above, or the public DoH resolvers listed above). The TLS inspector opens a live TLS connection to the hostname you submit and decodes the certificate returned by that host. IPSteak does not log the body of these requests.

IPSteak uses Google AdSense to display advertising. Google and its partners may use cookies, web beacons, IP addresses, device identifiers, and similar technologies to serve ads, measure ad performance, prevent fraud, and perform reporting. Where required by law, IPSteak presents a consent prompt before non-essential cookies or personalized advertising are enabled.

Cookies and advertising choices

IPSteak itself does not set first-party cookies for the IP lookup tool. Advertising partners may set or read cookies and similar identifiers. You can manage these through:

• The cookie or consent prompt presented on the site, where shown.
• Your browser's cookie and tracking-prevention settings.
• Google's ads settings at adssettings.google.com.
• The Global Privacy Control browser signal, which IPSteak honors where applicable and technically feasible.
• Industry opt-out tools such as youradchoices.com and youronlinechoices.eu.

How information is used

Technical information is used to operate the site, show connection details, maintain security, understand aggregate site performance, display advertising, and prevent abuse or invalid traffic.

How information is shared

IPSteak may share technical information with service providers that help operate the site, provide network lookup data, deliver ads, measure performance, detect fraud, comply with law, or protect the site and users. IPSteak does not sell personal information that you directly submit because the site does not collect account or form submissions.

Depending on where you live, state or federal privacy, consumer protection, and advertising laws may provide additional rights. To make a privacy request, email privacy@ipsteak.com and describe the request. IPSteak may need to verify the request before taking action.

Data retention

IPSteak aims to keep directly controlled personal data to a minimum. Server, security, analytics, and advertising records may be retained by hosting, security, advertising, or lookup providers according to their own retention practices.

Children

IPSteak is not directed to children. The site does not knowingly collect personal information from children under 13 in the United States, or under the applicable age of digital consent (which may be up to 16) in the European Economic Area, the United Kingdom, and other jurisdictions with similar rules.

Security

IPSteak uses reasonable technical measures for a static website, but no website or internet transmission can be guaranteed completely secure.

Changes

This policy may be updated as the site, advertising setup, or legal obligations change. The "Last updated" date above reflects the current version.
