UUID v4 Structure (128 bits)

Bytes 0–3 (time_low)

00010000 11001101 00011011 10110011

Bytes 4–5 (time_mid)

10011100 00101101

Bytes 6–7 (version + time_hi)

01001001 11101010

Bytes 8–9 (variant + clock_seq)

10000111 10100011

Bytes 10–15 (node)

01100100 01001110 01111110 00100011 01100101 01111110

Bits 48–51 (byte 6, high nibble): Version = 4

Bits 64–65 (byte 8, high bits): Variant = 10xx (RFC 4122)
