Hi Philipp, am I assuming correctly that you want to know on which IP address you received an incoming request?
An API extension for the underlying UDP SOCK API is about to get merged [1], that would allow just this. Still missing are implementations of that API (but the pull requests for those are open and likely much less controversial than an API extension) and an extension to gcoap to forward this info. I assume this is something that will land sooner or later in RIOT, as the ability to do virtual hosting based on IP address has some interesting use cases (e.g. to provide some resources only on the link-local IPv6 address, while other resources can also be provided to a wider audience). Kind regards, Marian [1]: https://github.com/RIOT-OS/RIOT/pull/14703 On Thu, 03 Dec 2020 05:49:23 +0100 Philipp Blum <[email protected]> wrote: > > Philipp Blum <[email protected]> wrote: > >> I need to get the IP address within gcoap.
