Sipcalc 是一个命令行 ip 子网计算器，支持 IPv4 和 IPv6，它会显示你填写 DHCP 信息或设置静态 IP 地址所需的所有 IP 相关信息。Sipcalc 的开发始于 2001 年，它具有我们想要的 ip 计算器的大部分功能。
安 装
在Centos8中安装sipcalc之前，需要先安装epel源。：
[root@localhost ~]# yum -y install epel-release [root@localhost ~]# yum -y install sipcalcsipcalc 使用方式
下面使用 sipcalc 列出一个标准 24 位的 C 类网络示例：
[root@localhost ~]# sipcalc 192.168.10.0/24 -[ipv4 : 192.168.10.0/24] – 0 [CIDR] Host address – 192.168.10.0 Host address (decimal) – 3232238080 Host address (hex) – C0A80A00 Network address – 192.168.10.0 Network mask – 255.255.255.0 Network mask (bits) – 24 Network mask (hex) – FFFFFF00 Broadcast address – 192.168.10.255 Cisco wildcard – 0.0.0.255 Addresses in network – 256 Network range – 192.168.10.0 – 192.168.10.255 Usable range – 192.168.10.1 – 192.168.10.254可以看到列出了192.168.10.0/24网段中广播地址、反掩码、网络范围和可用的IP地址范围。
下面添加-a查看一下：
[root@localhost ~]# sipcalc -a 192.168.10.0/24 -[ipv4 : 192.168.10.0/24] – 0 [Classful] Host address – 192.168.10.0 Host address (decimal) – 3232238080 Host address (hex) – C0A80A00 Network address – 192.168.10.0 Network class – C Network mask – 255.255.255.0 Network mask (hex) – FFFFFF00 Broadcast address – 192.168.10.255 [CIDR] Host address – 192.168.10.0 Host address (decimal) – 3232238080 Host address (hex) – C0A80A00 Network address – 192.168.10.0 Network mask – 255.255.255.0 Network mask (bits) – 24 Network mask (hex) – FFFFFF00 Broadcast address – 192.168.10.255 Cisco wildcard – 0.0.0.255 Addresses in network – 256 Network range – 192.168.10.0 – 192.168.10.255 Usable range – 192.168.10.1 – 192.168.10.254 [Classful bitmaps] Network address – 11000000.10101000.00001010.00000000 Network mask – 11111111.11111111.11111111.00000000 [CIDR bitmaps] Host address – 11000000.10101000.00001010.00000000 Network address – 11000000.10101000.00001010.00000000 Network mask – 11111111.11111111.11111111.00000000 Broadcast address – 11000000.10101000.00001010.11111111 Cisco wildcard – 00000000.00000000.00000000.11111111 Network range – 11000000.10101000.00001010.00000000 – 11000000.10101000.00001010.11111111 Usable range – 11000000.10101000.00001010.00000001 – 11000000.10101000.00001010.11111110 [Networks] Network – 192.168.10.0 – 192.168.10.255 (current)可以看到可以看到192.168.10.0网段的有类路由和无类路由的二进制形式。
下面使用一个27为掩码的网段：
[root@localhost ~]# sipcalc 192.168.10.0/27 -[ipv4 : 192.168.10.0/27] – 0 [CIDR] Host address – 192.168.10.0 Host address (decimal) – 3232238080 Host address (hex) – C0A80A00 Network address – 192.168.10.0 Network mask – 255.255.255.224 Network mask (bits) – 27 Network mask (hex) – FFFFFFE0 Broadcast address – 192.168.10.31 Cisco wildcard – 0.0.0.31 Addresses in network – 32 Network range – 192.168.10.0 – 192.168.10.31 Usable range – 192.168.10.1 – 192.168.10.30可以看到可用地址为192.168.10.1-192.168.10.30
添加-a选项，可以看到可用的网段有哪些：
[root@localhost ~]# sipcalc 192.168.10.0/27 -a -[ipv4 : 192.168.10.0/27] – 0 [Classful] Host address – 192.168.10.0 Host address (decimal) – 3232238080 Host address (hex) – C0A80A00 Network address – 192.168.10.0 Network class – C Network mask – 255.255.255.0 Network mask (hex) – FFFFFF00 Broadcast address – 192.168.10.255 [CIDR] Host address – 192.168.10.0 Host address (decimal) – 3232238080 Host address (hex) – C0A80A00 Network address – 192.168.10.0 Network mask – 255.255.255.224 Network mask (bits) – 27 Network mask (hex) – FFFFFFE0 Broadcast address – 192.168.10.31 Cisco wildcard – 0.0.0.31 Addresses in network – 32 Network range – 192.168.10.0 – 192.168.10.31 Usable range – 192.168.10.1 – 192.168.10.30 [Classful bitmaps] Network address – 11000000.10101000.00001010.00000000 Network mask – 11111111.11111111.11111111.00000000 [CIDR bitmaps] Host address – 11000000.10101000.00001010.00000000 Network address – 11000000.10101000.00001010.00000000 Network mask – 11111111.11111111.11111111.11100000 Broadcast address – 11000000.10101000.00001010.00011111 Cisco wildcard – 00000000.00000000.00000000.00011111 Network range – 11000000.10101000.00001010.00000000 – 11000000.10101000.00001010.00011111 Usable range – 11000000.10101000.00001010.00000001 – 11000000.10101000.00001010.00011110 [Networks] Network – 192.168.10.0 – 192.168.10.31 (current) Network – 192.168.10.32 – 192.168.10.63 Network – 192.168.10.64 – 192.168.10.95 Network – 192.168.10.96 – 192.168.10.127 Network – 192.168.10.128 – 192.168.10.159 Network – 192.168.10.160 – 192.168.10.191 Network – 192.168.10.192 – 192.168.10.223 Network – 192.168.10.224 – 192.168.10.255原文链接：https://mp.weixin.qq.com/s/ks6RnG5eOkJyHYSjgIwv_w
