UUID v4 Structure (128 bits)

Bytes 0–3 (time_low)

10011010 00001010 01100010 01011101

Bytes 4–5 (time_mid)

11101010 11000000

Bytes 6–7 (version + time_hi)

01001100 01101101

Bytes 8–9 (variant + clock_seq)

10011111 10001100

Bytes 10–15 (node)

00010101 00101101 00101001 00000111 00111011 00100010

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

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

• Remaining 122 bits are cryptographically random (v4)
