Not the one I want.
Ah, I forgot, you wanted the external address, sorry.
No, the internal.
I meant external as opposed to link-local. There is no more internal/external, your machines all have public ipv6 addresses.
The external I can ask some web pages, and maybe the router itself.
Yep, got it - you want the LAN side address of the router.
That's today's address, the ISP "promised" to use dynamic prefixes.
Which isn't the same as a guaranteed change, I expect.
Every time the rooter reboots, same as with IPv4.
Really? That is not how most providers do it.
Notice the losses. Same as with IPv4.
Try increasing the interval, the default is 10ms.
Why? :-?
To avoid having packets dropped. ICMPs may be dropped, they have the lowest priority. If you are flood pinging your network - which I suggest 100 pings per second is - some will be dropped. -- Per Jessen, Zürich (15.6°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
