I’m currently on vacation in Phuket Thailand, and discovered for YaST Software Manager for Packman updates, and for Firefox for some websites I had to disable ipv6 to obtain access. I did not have the same problem (in accessing these sites) with Chrome browser that I had with firefox.
For example, with ipv6 enabled this is the error I received with YaST Software Package manager on my 64-bit openSUSE-12.1 KDE desktop :

and with ipv6 enabled when I type the Packman URL in Firefox I obtain this error:

Yet Chrome works with ipv6 enabled the same site (making me think Chrome does something special wrt ipv6):

… so I then disabled ipv6 on my openSUSE-12.1 install and rebooted, and then noted firefox for the same site works:

I then tested YaST software manager and it also works fine with ipv6 disabled on my openSUSE-12.1.
Note in Germany, for the same site with the same laptop computer and same boot partition (to openSUSE-12.1), ipv6 works fine. So somewhere between my computer wireless connecting to my brother-in-law’s home router (connected to a Thai ISP), and the Packman (and other) sites, it appears that ipv6 causes a problem (that is a bit speculative on my part).
Anyway, I am relieved to note that this works by disabling ipv6.
