我在制定网络子网时非常糟糕.是否有一些
Linux命令行工具(ubuntu包加一个),这让我输入255.255.255.224它会告诉我这是/ 27？
解决方法
ipcalc可以做到这一点,例如：
[kbrandt@kbrandt-opadmin: ~] ipcalc 192.168.1.1/24 Address: 192.168.1.1 11000000.10101000.00000001. 00000001 Netmask: 255.255.255.0 = 24 11111111.11111111.11111111. 00000000 Wildcard: 0.0.0.255 00000000.00000000.00000000. 11111111 => Network: 192.168.1.0/24 11000000.10101000.00000001. 00000000 HostMin: 192.168.1.1 11000000.10101000.00000001. 00000001 HostMax: 192.168.1.254 11000000.10101000.00000001. 11111110 Broadcast: 192.168.1.255 11000000.10101000.00000001. 11111111 Hosts/Net: 254 Class C,Private Internet
如果您输入子网掩码而不是CIDR,您仍会在“网络：”之后看到/ ## CIDR编号,因此它会双向进行.
或与sipcalc：
[kbrandt@kbrandt-opadmin: ~] sipcalc 192.168.1.1/24 <23403@8:55> -[ipv4 : 192.168.1.1/24] - 0 [CIDR] Host address - 192.168.1.1 Host address (decimal) - 3232235777 Host address (hex) - C0A80101 Network address - 192.168.1.0 Network mask - 255.255.255.0 Network mask (bits) - 24 Network mask (hex) - FFFFFF00 Broadcast address - 192.168.1.255 Cisco wildcard - 0.0.0.255 Addresses in network - 256 Network range - 192.168.1.0 - 192.168.1.255 Usable range - 192.168.1.1 - 192.168.1.254
Ubuntu包是ipcalc和sipcalc：
sudo apt-get install ipcalc sudo apt-get install sipcalc
