Convert mac address 48 bit python4/15/2023 Step 3: Change the format to use a colon delimiter: 0015:2BFF:FEE4:9B60. Step 2: Insert FF:FE in the middle: 4.9B60. Hardware address means the MAC address of a network interface. If all attempts to obtain the hardware address fail, we choose a random 48-bit number with the multicast bit (least significant bit of the first octet) set to 1 as recommended in RFC 4122. Step 1: Split the MAC address in the middle: 0015.2B E4.9B60. The first time this runs, it may launch a separate program, which could be quite slow. UUID ( '' ) # convert a UUID to a string of hex digits in standard form > str ( x ) '00010203-0405-0607-0809-0a0b0c0d0e0f' # get the raw 16 bytes of the UUID > x. The objective is to calculate the corresponding EUI-64 address based on this MAC address. When a string of hex digits is given, curlyīraces, hyphens, and a URN prefix are all optional. Time_mid, 16-bit time_hi_version, 8-bit clock_seq_hi_variant, 8-bitĬlock_seq_low, 48-bit node) as the fields argument, or a single 128-bit The bytes_le argument, a tuple of six integers (32-bit time_low, 16-bit UUID ( ] ] ] ] ] ) ¶Ĭreate a UUID from either a string of 32 hexadecimal digits, a string of 16īytes as the bytes argument, a string of 16 bytes in little-endian order as Note that uuid1() may compromise privacy since it createsĪ UUID containing the computer’s network address. If all you want is a unique ID, you should probably call uuid1() or Generating version 1, 3, 4, and 5 UUIDs as specified in RFC 4122. This module provides immutable UUID objects (the UUID class)Īnd the functions uuid1(), uuid3(), uuid4(), uuid5() for uuid - UUID objects according to RFC 4122 ¶
