oh good question! The Meetecho folk dropped off gear, so I assume so :)

it looks like the meetecho site doesn't show this though :(

Can the ticket folk please ask the meetecho folk to make the IEPG
meeting stream?

#1240 duplicate v6 advertised on ietf-hotel but doesn't work? Clemens Schrimpe jari.arkko@…
Description

Hi,

Wondering if this is a problem or something on my Mac…

When connected to the “ietf” SSID on floor 9, I get everything working nicely. But when connecting to “ietf-hotel”, again everything works nicely on v4, but on v6 I have no connectivity.

Yet there’s a prefix advertisement:

11:46:01.542449 IP6 (hlim 255, next-header ICMPv6 (58) payload length: 96) fe80::46d9:e7ff:fe40:b938 > ff02::1: [icmp6 sum ok] ICMP6, router advertisement, length 96
	hop limit 64, Flags [other stateful], pref medium, router lifetime 600s, reachable time 0s, retrans time 0s
	  prefix info option (3), length 32 (4): 2001:67c:1232:144::/64, Flags [onlink, auto], valid time 2592000s, pref. time 2592000s

	    0x0010:  067c 1232 0144 0000 0000 0000 0000

	    0x0000:  0000 0000 000f 2001 067c 0370 0229 0000
	    0x0010:  0000 0000 0007 2001 067c 0370 0229 0000
	    0x0020:  0000 0000 0006

	    0x0000:  44d9 e740 b938

Which is accepted by my Mac, but then pinging on v6 doesn’t work.

Is ietf-hotel supposed to work on v6? If not, disable the advertisements… if yes… maybe some fixing to do on my Mac or your network...

howdy!
I noticed that i can't ping (ipv6 ping) a bunch of things like:
  ~$ ping ipv6.google.com
PING ipv6.google.com(sin10s02-in-x0e.1e100.net (2404:6800:4003:80d::200e))

I thought (until the third item) that this was my fault ... but! I think
it's not (at least not for the reason I originally thought)... I also can't
connect over ipv6 to services which SHOULD be running, like:
  $ telnet ipv6.google.com 443
Trying 2404:6800:4003:80d::200e...
^C


 $  telnet www.google.com 443
Trying 2404:6800:4003:80d::2004...
^C


$ telnet mailserver.ops-netman.net 22
Trying 2606:700:e:550:b00b::b00b...
^C


I CAN connect to these from a point not on the current IETF network:
$ telnet mailserver.ops-netman.net 22
Trying 2606:700:e:550:b00b::b00b...
Connected to mailserver.ops-netman.net.
Escape character is '^]'.

morrowc@mailserver:~$ telnet 2404:6800:4003:80d::200e 443
Trying 2404:6800:4003:80d::200e...
Connected to 2404:6800:4003:80d::200e.

^C


etc... I'm currently connected like:
