An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.

WebDec 16, 2010 · The first thing you'd notice in an ipv6 header is that, there are no IP ID or Fragmentation Offset fields as in ipv4. Also, with ipv6, there is no hop-by-hop ip fragmentation (it's only performed by the source node), so the concept for pre-fragmentation, or fragmentation in general on an IPSec tunnel endpoint, really doesn't apply to ipv6.
