UUID v4 Structure (128 bits)

Bytes 0–3 (time_low)

10111110 11111101 01011111 01011111

Bytes 4–5 (time_mid)

01100101 01001000

Bytes 6–7 (version + time_hi)

01000000 00011000

Bytes 8–9 (variant + clock_seq)

10100111 00011101

Bytes 10–15 (node)

00000011 01000101 10000111 10010000 01110100 00111100

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)
