在进行域名投资、网络安全调查、品牌保护或日常运维时，一个支持广泛顶级域名（TLD）后缀的 WHOIS 查询工具至关重要。市面上许多工具仅支持.com、.net、.org等常见后缀，一旦遇到新 gTLD（如.app、.dev）或国家代码域名（如.cn、.jp），便无能为力。
今天，我们隆重介绍OneFour—— 一款专业、免费、极速且全面支持全球顶级域名的 WHOIS 查询平台。根据官方数据，OneFour 当前已支持 1436 个顶级域名后缀，几乎覆盖了 IANA（互联网号码分配机构）注册的所有公开 TLD。
🔍 为什么支持广泛的 TLD 如此重要？
- 域名投资者：需要查询
.xyz、.top、.club等新后缀的注册状态和历史。 - 安全研究人员：常需分析钓鱼网站使用的冷门后缀，如
.ga、.ml、.tk。 - 跨国企业：必须监控
.de（德国）、.fr（法国）、.co.uk（英国）等区域品牌域名。 - 开发者：调试
.io、.ai、.tech等技术社区流行域名时，需准确 WHOIS 信息。
OneFour 不仅支持上述所有场景，还兼容大量品牌专属域名（如.google、.apple、.alibaba）和国际化域名（IDN）（如.中国、.游戏）。
✅ OneFour 的核心优势
- 完全免费：无需注册，无查询次数限制。
- 多语言界面：支持中、英、日、韩、德、法、俄等多国语言。
- 移动端友好：PWA 应用，可安装到手机桌面，体验如原生 App。
- 隐私优先：不记录用户查询的敏感信息。
- IP 关联分析：唯一支持 “IP → 历史绑定域名” 反查的免费工具。
📋 全量支持的顶级域名后缀列表（共 1436 个）
为了方便您确认目标后缀是否被支持，并提升本文在搜索引擎中的可见性，我们在此完整列出 OneFour 支持的所有顶级域名（TLD）。无论您要查询的是.academy还是.zone，是.政务.cn还是.xn--fiqz9s（“中国”），只要在以下列表中，OneFour 都能为您提供准确的 WHOIS 信息。

Ctrl+F（Windows）或Cmd+F（Mac）快速搜索特定后缀。
