例如,我正在寻找一种转换 IPV6 地址的方法
fe80::1d81:b870:163c:5845
使用 Python 转换为 MAC 地址。所以输出应该是
1f:81:b8:3c:58:45
就像在这个页面上:http://ben.akrin.com/?p=4103 如何将 IPV6 转换为 MAC?
请您参考如下方法:
这里有两个函数可以进行两种方式的转换。
检查给定参数是否为正确的 MAC 或 IPv6 也可能很有用。
从MAC到IPv6
def mac2ipv6(mac):
# only accept MACs separated by a colon
parts = mac.split(":")
# modify parts to match IPv6 value
parts.insert(3, "ff")
parts.insert(4, "fe")
parts[0] = "%x" % (int(parts[0], 16) ^ 2)
# format output
ipv6Parts = []
for i in range(0, len(parts), 2):
ipv6Parts.append("".join(parts[i:i+2]))
ipv6 = "fe80::%s/64" % (":".join(ipv6Parts))
return ipv6
从IPv6到MAC
def ipv62mac(ipv6):
# remove subnet info if given
subnetIndex = ipv6.find("/")
if subnetIndex != -1:
ipv6 = ipv6[:subnetIndex]
ipv6Parts = ipv6.split(":")
macParts = []
for ipv6Part in ipv6Parts[-4:]:
while len(ipv6Part) < 4:
ipv6Part = "0" + ipv6Part
macParts.append(ipv6Part[:2])
macParts.append(ipv6Part[-2:])
# modify parts to match MAC value
macParts[0] = "%02x" % (int(macParts[0], 16) ^ 2)
del macParts[4]
del macParts[3]
return ":".join(macParts)
例子
ipv6 = mac2ipv6("52:74:f2:b1:a8:7f")
back2mac = ipv62mac(ipv6)
print "IPv6:", ipv6 # prints IPv6: fe80::5074:f2ff:feb1:a87f/64
print "MAC:", back2mac # prints MAC: 52:74:f2:b1:a8:7f
