Hi
Hast anybody at Cisco already realized that the URL shortener of Cisco is announced with an AAAA DNS record but does not answer to IPv6 connection requests? I only get SYN-timeouts. On IPv4 it's not a problem at all. :-)
Just an example: http://cs.co/cucm10
Kind regards
Roberto

Roberto,
Good find, doesn't respond on port 80 or 443. Can you please submit feedback to team handling that one. There's a feedback button at the bottom of the cs.co page, just don't to it over IPv6 ;].
We don't really deal with that here on support forums.

Disabling IPv6 to do a legacy IPv4 access, just to test and open service requests? Well that's something we will see more often during the transition phase. Therefore I think somehow it matches into this support forum. ;-)
It turned out to be quite hard to find an IPv4 system at my place. But I filed the feedback. I'm just wondering if the ones reading it will understand what the problem is.

Roberto,
There is IP and legacy IP ... :-)
I submitted feedback too. I _think_ it's the same group as the ones handling cisco.com ... if it is they are pretty responsive. If not ... we at least tried.
