📜 Changelog
- Added: hover any geographic coordinates on the page (e.g.
25.0478, 121.5319) to see the location on Google Maps, with one click to open it there. - Added: coordinate fields inside the IP card are now clickable map links.
- Added: a privacy statement at the foot of the page covering what is not collected, how caching and rate limiting actually work, and which third-party sources are used.
- Added: hover any IP anywhere on the page — not just clickable links, but plain-text fields such as the queried IP, IP address and reverse hostname — to see its full details — country, region, ISP, organization, ASN and reverse hostname — without copying it into the search box.
- Improved: each IP is looked up once and cached, so repeat hovers are instant; move into the card to select text, press Esc to close.
- Fixed: looking up a subdomain (e.g.
waste.ifu-move.com) returned "No match" from the registry WHOIS — which only holds registrable domains — and was reported as available. The tool now falls back to the parent domain and says so. - Added: when WHOIS has no record but the domain resolves in DNS, it is always reported as registered.
- Improved: you can paste a full URL including scheme, path and port.
- Added: Simplified Chinese
/domain/cn/and Japanese/domain/ja/versions; switch between four languages from the top-right corner (Traditional Chinese is the default). - SEO: each language has its own URL, canonical and hreflang (zh-Hant-TW / zh-Hans / en / ja), with Traditional Chinese as x-default.
- Improved: the lookup field now sticks to the top of the screen while you scroll through long results.
- Added: a one-click copy button next to "Your IP address"; the logo and page title now link to the main site and the tool home.
- Added: a full English interface with an instant language switcher in the top-right corner.
- SEO: the English version uses a dedicated URL
/domain/en/rendered server-side, so Google can fully index the English content. - SEO: added hreflang, canonical and JSON-LD structured data to declare the Chinese/English language relationship.
- Improved: precise Google Tag Manager (GTM) deployment.
- Improved: dedicated SEO meta description to boost search click-through.
- Added: append an IP or domain to the URL (e.g.
/domain/8.8.8.8) to auto-run the smart lookup on page load.
All-in-one domain lookup service
This domain lookup tool lets you run WHOIS lookups, DNS record queries, IP geolocation and domain availability checks from a single screen. Just enter a domain name, URL or IP address and the tool automatically detects the type and returns the registrar, expiry date, name servers, resolved IPs and other registration details so you can understand a domain's status and history at a glance.
🔒 Privacy statement
No account or sign-in is required. We do not collect your name, email or any personal contact details, we do not build user profiles, and we never sell or share data for marketing purposes.
- What you type is never linked to your identity, and lookup history is not stored.
- To speed up responses and reduce load on upstream services, lookup results are cached on the server keyed by the query itself (IP and WHOIS 6 hours, DNS 5 minutes). Cached entries contain no information about who ran the lookup.
- Abuse protection stores only an irreversible hash of the source IP plus a request count — never the raw IP.
- The time and source IP are recorded only when a system error occurs, for troubleshooting.
- Lookups are forwarded to public data sources (WHOIS / RDAP registries, ip-api.com, ipinfo.io, ipwhois.app) to obtain results.
- This site uses Google Tag Manager for anonymous traffic statistics.
