如何将 IPv6 link-本地地址转换为 Python 中的 MAC 地址
How to convert IPv6 link-local address to MAC address in Python
我正在寻找一种转换 IPV6 地址的方法,例如
fe80::1d81:b870:163c:5845
进入一个 MAC-地址 Python。所以输出应该是
1f:81:b8:3c:58:45
就像这个页面上的一样:http://ben.akrin.com/?p=4103
如何将 IPV6 转换为 MAC?
这里有两个函数可以双向转换。
检查给定参数是否正确 MACs 或 IPv6s 可能也很有用。
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
