Server Side Tools
49 tools available
These tools need our server to find their answer: they look up DNS, WHOIS, and RDAP records, locate and check IP addresses, verify TLS certificates and redirects, ping Minecraft, Counter-Strike, and other game servers, or check a hostname against blocklists. What you enter is sent to our server, which runs the lookup and sends back the result.
Identify the manufacturer or vendor of a network device by looking up its MAC address.
Resolve IPv4 and IPv6 addresses for a domain using fixed server-side DNS providers.
Look up the geographic location of any IP address, including country, region, city, timezone, and coordinates.
Look up WHOIS and RDAP registration data for any domain, including registrar, registrant, nameservers, and expiry date.
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 any YouTube video for community-submitted SponsorBlock segments (sponsor spots, intros, outros, and more).

Check your current public IP address (IPv4 and IPv6) and view your fetch history.
Check whether an IP address belongs to a known VPN provider or datacenter network.
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.
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.
Connect to a host and port to inspect its TLS/SSL certificate — expiry, trust status, full chain, protocol, and cipher suite.
Fetch an RSS or Atom feed by URL and preview its title, description, and items.
Look up RDAP registration data for any domain, including registrar, registrant, nameservers, and expiry date.
Validate a domain's SPF, DKIM, and DMARC DNS records to check email authentication and spot misconfigurations.
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.
