Hi,

  • Does RIOT support fragmentation in IPv6?

  • Does RIOT support IPv4? If so, does it support fragmentation in IPv4?

Thanks, Adel

Hi Adel,

And welcome to the RIOT community!

Hi,

  • Does RIOT support fragmentation in IPv6?

With https://github.com/RIOT-OS/RIOT/pull/11596 and https://github.com/RIOT-OS/RIOT/pull/11623 merged, fragmentation is supported by RIOT’s default network stack, GNRC.

  • Does RIOT support IPv4? If so, does it support fragmentation in IPv4?

GNRC does not support IPv4. However you can use LwIP as an alternative. AFAIK it supports fragmentation, but I am not 100% sure.

Might I ask what you need fragmentation for?
