I agree. Proof or not better ways exist to handle the problem.

Why not just use shifts and remove the b[] array ?

  (a[0] << 24) | (a[1] << 16) | (a[2] << 8) | (a[3] << 0)

Is the code ok for network byte order ?

May be the string is turned into a '.' address and then inet_addr (or similar) 
parsed.
