IPv6 Parser | Dataford Interview Questions

Write an IPv6 parser. Example input 1234:abcd:0000:0000:0102:0000:00... should produce a byte array ending [..., 0, 0, 192, 128, 0, 1].

Asked in the onsite round 1 stage. The sample address and the tail of the expected byte array are quoted in the post; the middle is cut off by the points wall.

Implement def ipv6_to_bytes(address):. The input is a valid IPv6 address using hexadecimal groups and optional :: compression. Return a list of exactly 16 integers in network byte order, with values from 0 through 255.

Constraints

The input is a valid IPv6 address.
The address contains exactly eight 16-bit groups after expanding ::.
Each explicit group contains 1 to 4 hexadecimal characters.
At most one :: appears in the input.
Return exactly 16 integers, each in the range 0 through 255.

Function Signature
