方法1 ・使用 arp-scan
方法1 ・使用 arp-scan
arp-scan 是一個專門用來掃描區域網段中活動的 IP 和 MAC 位址的工具。
安裝 arp-scan：
bash
複製程式碼
brew install arp-scan
使用 arp-scan 掃描：
bash
複製程式碼
sudo arp-scan --localnet
這將掃描當前區域網絡中的所有設備，並顯示它們的 IP 和 MAC 位址。
sudo arp-scan --localnet

方法2 使用 nmap
方法2 使用 nmap
nmap 是一個功能強大的網路掃描工具。你可以通過 Homebrew 來安裝它。
安裝 nmap：
bash
複製程式碼
brew install nmap
掃描區域網段內的所有 IP：
假設你的區域網段是 192.168.1.0/24，你可以運行以下指令：
bash
複製程式碼
nmap -sn 192.168.1.0/24
這將顯示該網段中所有活動的設備，主機名稱跟IP。
nmap -sn 192.168.0.0/24

方法
3. 使用 ping 掃描（基本方法）
這種方法比較簡單，但不如上面兩個工具強大。你可以使用 ping 循環遍歷整個網段。
範例腳本：
bash
複製程式碼
for ip in $(seq 1 254); do ping -c 1 192.168.1.$ip | grep "64 bytes" & done
這將嘗試 ping 192.168.1.1 到 192.168.1.254 的所有 IP，並顯示有回應的 IP。
小結：
小結：
nmap 和 arp-scan 是更專業和強大的工具，能夠提供更完整的網路掃描資訊。
ping 適合小規模的簡單掃描，但對於大型網段可能效率不高。
