IPv6 Has nothing to do with frame sizes (except that too large packets now get dropped instead of being fragmented into two parts)

- geofft 11y agoIPv4 lets the MTU get as low as 68 (but you're only sending 8 bytes of data per packet); IPv6 prevents it from getting any lower than 1280, but permits "link-specific fragmentation and reassembly" as long as IPv6 itself doesn't see any smaller fragments. IPv6 also permits (but does not require) jumbograms that make full use of the 32-bit packet size field, but across a wireless link, having to retransmit 4 GB at a time seems like a bad plan... this only seems useful for short-distance wired connections among hosts that know they've got a quality cable between them.
