Not the one I want.
Ah, I forgot, you wanted the external address, sorry.
Where do you expect the word "router" to come from, from the DNS server? :-?
No, it is a 'role' dished out with ICMPv6 RAs. Your router basically broadcasts its address as the router for the local network.
Ok, so the router address is 2a02:9140:...:ceed:dcff:fe05:80d4. I found the correct address yesterday, with my convoluted method.
That's today's address, the ISP "promised" to use dynamic prefixes.
Which isn't the same as a guaranteed change, I expect.
I run this from the server, 24*7:
while sleep 1 ; do DATE=`date --iso=s` ; echo -n "$DATE " ; \ fping -c 100 --quiet 2a02:...ceed:dcff:fe05:80d4 ; \ done
Result:
2023-04-18T11:37:23+02:00 2a02:...80d4 : xmt/rcv/%loss = 100/75/25%, min/avg/max = 0.45/0.58/0.92 [snip]
Notice the losses. Same as with IPv4.
Try increasing the interval, the default is 10ms. -- Per Jessen, Zürich (14.6°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
