网工快查 vs Net Diagnostic Toolbox

网工快查是一款面向弱电师傅、家庭网络维护、小型办公室和门店网络维护人员的 iOS 网络诊断工具。 它不是大型企业网管工具。App 聚焦日常排障：打开后即可一键检测当前 Wi-Fi、局域网和外网状态，并生成可分享的维护报告。 主要功能： - 一键诊断当前网络、本机 IP、子网、网关、DNS、外网连接和公网 IP - 自动生成专业分析：子网容量、DNS 一致性、设备变化、敏感服务暴露、关键设备离线和现场行动清单 - 发现当前局域网设备，标记本机、网关、疑似路由器、打印机、NAS、摄像头等常见角色 - 收藏关键设备、记录维护备注，并在后续诊断中对比新增设备和关键设备离线情况 - 检测单个 IP 或域名的常用服务可达性，并显示耗时和错误原因 - 根据开放端口给出 Telnet、远程桌面、SMB、RTSP、打印、NAS 管理等服务风险解读 - 支持 A、AAAA、CNAME、MX、NS、TXT DNS 查询，以及多个 DNS 结果对比 - 内置子网计算器、现场排障剧本和交付检查清单 - 检测公网 IPv4/IPv6 和运营商/归属地信息，并保留本地历史 - 一键生成文本报告，支持导出 PDF 或图片，报告包含专业分析和行动清单 - 支持填写客户名称、项目名称和维护人员名称 所有报告、设备备注、收藏和历史记录默认保存在本机，不上传到自有服务器。由于 iOS 系统限制，普通 App 无法读取局域网设备 MAC 地址和 ARP 表，也无法发送原始 ICMP ping；网工快查会在系统允许范围内通过网络接口信息、DNS 查询、HTTPS 外网检测和常用服务可达性完成诊断。
