NetAddr::MAC->new( mac => $mac )Ĭreates and returns a new NetAddr::MAC object. It can be called in any of the following ways. The new method creates instances of this object. ZigBee / 802.15.4 wireless personal-area networks OO METHODS new Some networks that use Extended Unique Identifier 64 addresses include: Firewire Some networks that use Extended Unique Identifier 48 (or MAC48) addresses include: Ethernet Although the most common case is hardware addresses on Ethernet network cards, there are a variety of devices that use this system of addressing.īoth Extended Unique Identifier 48 and 64 addresses are supported. These are the addresses that uniquely identify a device on various layer 2 networks. This module provides an OO and functional interface to deal with Media Access Control (or MAC) addresses.

Sometimes you can express an algorithm in a very concise and readable way, but avoid code-golfing for the sake of compactness.
Convert mac address to ipv6 address code#
In Python, we usually don't strive for shorter code we aim for readable code. I followed the PEP 8 whitespace recommendations to format the code here whitespace around operators and after commas, for example. # XOR the most significant byte with 0x02, inverting the # Split out the bytes that slot into the IPv6 address # Remove the most common delimiters dots, dashes, etc. In this case, I'd actually split out the various bytes of the MAC address binary value that make up the IPv6 parts, and use str.format() to interpolate those into the IPv6 string. Use the format() function instead, as it gives you much more control over the output.įor example, format(value, '012x') formats the integer value to a 12-digit hexadecimal (using lowercase digits), padding out the result to the minimum width with leading zeros as needed: > mac_value = 0x237702d2ff9b Note that the purpose of the hex() function is to produce a hexadecimal integer literal (a string that can be used in Python source code), which is why it returns a hex value with the 0x prefix. # Remove/slice the '0x' off the begining from using hex(). # use xor of 02 on the 2nd most significant hex char. # cast the hex string to an base-16 int for math safety. # remove the most common macaddr delimiters, dots, dashes, etc. #!/usr/bin/pythonĬonvert mac addr to ipv6 link local (rfc 4862) I'm using python 2.7, but my Linux distro is soon to switch to 3.x.
