answer:可以使用golang的net包中的Subnet函数来获取指定IP段的所有IP地址。具体实现如下： ```go package main import ( "fmt" "net" ) func main() { ip := net.ParseIP("192.168.1.1") mask := net.CIDRMask(16, 32) netIP := ip.Mask(mask) for ip := netIP.Mask(mask); mask.Contains(ip); inc(ip) { fmt.Printf("%sn", ip.String()) } } func inc(ip net.IP) { for j := len(ip) - 1; j >= 0; j-- { ip[j]++ if ip[j] > 0 { break } } } ``` 在上面的代码中，我们首先解析了指定的IP地址为一个net.IP类型，并使用net.CIDRMask函数创建一个网络掩码。接着，使用net.IP的Mask方法获取了B段的网络地址netIP，并循环遍历所有可能的IP地址，并逐一输出。 以上代码会输出B段中所有的IP地址，从192.168.0.0到192.168.255.255。

answer:masscan是一款高速的端口扫描工具，可以快速扫描大量主机和端口。以下是使用masscan扫描一个B段所有2375端口的命令： ``` masscan 192.168.1.1/16 -p2375 -oG scan.txt ``` 以上命令中，我们使用了192.168.1.1/16这个B段地址作为扫描目标，只扫描了2375端口。同时，我们将扫描结果保存到了一个名为scan.txt的文件中。 需要注意的是，2375端口是Docker的开放端口，若您没有使用Docker或有其他用途，可以根据您的需要进行改变。同时，使用masscan可能会对您的网络造成一定的负担，请务必谨慎操作。
