Ciscos URL shortener not answering to IPv6

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, 

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. 

 

$ host cs.co

cs.co has address 67.192.93.178

Disabling IPv6 to do a legacy

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

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.
