这是一种笨方法，是根据系统内置命令去获取的。我只是抛砖引玉，希望有人给我分享更好的代码，比如通过ARP协议去获取MAC地址？

class IP2MAC:

def __init__(self):

self.patt_mac = re.compile(‘([a-f0-9]{2}[-:]){5}[a-f0-9]{2}’, re.I)

def getMac(self, ip):

sysstr = platform.system()

if sysstr == ‘Windows’:

macaddr = self.__forWin(ip)

elif sysstr == ‘Linux’:

macaddr = self.__forLinux(ip)

else:

macaddr = None

return macaddr or ’00-00-00-00-00-00′

def __forWin(self, ip):

os.popen(‘ping -n 1 -w 500 {} > nul’.format(ip))

macaddr = os.popen(‘arp -a {}’.format(ip))

macaddr = self.patt_mac.search(macaddr.read())

if macaddr:

macaddr = macaddr.group()

else:

macaddr = None

return macaddr

def __forLinux(self, ip):

os.popen(‘ping -nq -c 1 -W 500 {} > /dev/null’.format(ip))

result = os.popen(‘arp -an {}’.format(ip))

result = self.patt_mac.search(result.read())

return result.group() if result else None

if __name__ ==’__main__’:

g = IP2MAC()

print(g.getMac(‘192.168.112.80’), g.getMac(‘192.168.1.254′), sep=’\n’)
