## 子网掩码计算器 Description
子网掩码计算器是一款简洁、专业的网络计算工具,为网络工程师、运维人员、CCNA/HCIA 备考学生和开发者打造。输入一个 IP 地址和前缀(或 CIDR),立即得到所有你需要的子网信息。

【IPv4 计算】
• 网络地址、广播地址
• 可用主机范围与可用主机数
• 子网掩码、通配符(反掩码)、十六进制掩码
• 地址类别(A/B/C/D/E)与用途识别(私有 / 公网 / 环回 / 链路本地 / 组播 等)
• 二进制视图,网络位与主机位用颜色区分
• 掩码 ⇄ CIDR 前缀自由互转
• 正确处理 /31(点到点)、/32(单主机)等边界情况

【IPv6 计算】
• 地址压缩(::)与完整展开
• 地址类型识别(全球单播 / 链路本地 / 唯一本地 / 组播 等)
• 网络前缀、首地址、末地址
• 地址总数(以 2 的幂和精确数值显示)、/64 子网数量

【子网划分】
• 等分划分:把一个网段按新前缀平均切分,列出每个子网
• VLSM 变长子网划分:按每个子网所需主机数自动分配最合适的网段

【为什么选它】
• 100% 离线运行,不联网、不收集任何数据,保护隐私
• 点按任意结果即可一键复制
• 支持深色模式,iPhone 与 iPad 通用
• 中英双语,跟随系统语言
• 界面干净,没有广告打扰

无论是规划网络、做实验、备考还是日常排错,这款工具都能帮你又快又准地完成子网计算。
