title: Is network byte order pointless under IPv6?
body: <p>If we use a 32-bit integer to store an IPv4 address, then the byte order of the integer must be considered.</p>
  
  <p>However, as there is no built-in 128-bit integer type under almost all platforms, an IPv6 address must be stored into a byte array, so, I think the byte order is no longer a problem.</p>
  
  <p>Am I correct? Or is there a corresponding function htonlXXX for IPv6?</p>
