Look up WHOIS and RDAP registration data for any domain, including registrar, registrant, nameservers, and expiry date.

Look up RDAP registration data for any domain, including registrar, registrant, nameservers, and expiry date.

Check how old a domain name is by looking up its WHOIS registration date. See the exact age in years, months, and days, along with registrar and expiry details.

Check when a domain name will expire, including days remaining, registrar, and registration dates.

Check whether a domain name is available to register or already taken. Runs a live WHOIS lookup and shows registrar, creation, and expiry details when the domain is registered.

Resolve IPv4 and IPv6 addresses for a domain using fixed server-side DNS providers.

Validate a domain's SPF, DKIM, and DMARC DNS records to check email authentication and spot misconfigurations.

Find the subdomains of a domain using DNS records. The tool reads the domain's NS, MX, SOA, SRV, and SPF records and checks 350 common names like www, mail, api, and dev, then lists each subdomain with its IP addresses and CNAME target. Wildcard records are detected.

Check your current public IP address (IPv4 and IPv6) and view your fetch history.

Look up the geographic location of any IP address, including country, region, city, timezone, and coordinates.

Find the autonomous system number (ASN) of any IPv4 or IPv6 address. See the AS name, the organization that runs the network, the BGP prefix the address is routed in, and the registry, country, and dates of both.

Check whether an IP address belongs to a known VPN provider or datacenter network.

See how far a website or IP address is from you on a map. The tool resolves the domain's IP addresses over DNS, geolocates each server, and shows the distance and the theoretical minimum ping from your location.

Connect to a host and port to inspect its TLS/SSL certificate — expiry, trust status, full chain, protocol, and cipher suite.

Check where a URL redirects. See every hop of the redirect chain with its status code, such as 301, 302, 307, or 308, its IP address, and its response time, and find redirect loops and the final URL. Up to 10 redirects are followed.

Identify the web server software running on a host via a GET request to its index page.

Enter a website URL and the server fetches and validates its robots.txt, showing sitemaps, crawl delay, and preferred host.

Preview how a URL will look when shared on Facebook, Twitter/X, LinkedIn and other platforms by inspecting its Open Graph and Twitter Card meta tags.

Fetch a page and check its hreflang tags for missing x-default, invalid language codes, duplicates, and self-referencing errors.

Enter a URL and the server fetches the page, extracts every JSON-LD structured data block, and checks it for JSON syntax errors, missing @context and @type, unknown schema.org types and properties, and fields Google needs for rich results.

Fetch an RSS or Atom feed by URL and preview its title, description, and items.

Check whether a hostname or website is on the StevenBlack hosts blocklist, the full list with adware, malware, fake news, gambling, porn, and social media domains.

Check whether a hostname or website is blocked by HaGeZi's Multi ULTIMATE DNS blocklist, the largest tier with ads, trackers, telemetry, phishing, malware, and scams, and see which entry blocks it.

Check whether a hostname or website is blocked or targeted by EasyList, EasyPrivacy, and Fanboy's Annoyance List, and see every filter that blocks it, hides elements on it, or allows it.

Check the status of a Minecraft Java Edition server: MOTD, version, protocol, online and max players, and server icon.

Check the status of a Counter-Strike 1.6 server: name, current map, online players, bots, server type, VAC status, and connected player list.

Check the status of a San Andreas Multiplayer (SA-MP) server: hostname, gamemode, language, online players, password protection, connected player list, and server rules.

Check the status of a GTA 5 FiveM server, including player count, game type, map, resources, and connected players.

Check the estimated like and dislike counts for any YouTube video, restored via the Return YouTube Dislike API.

Check any YouTube video for community-submitted SponsorBlock segments (sponsor spots, intros, outros, and more).

Identify the manufacturer or vendor of a network device by looking up its MAC address.
