MarkoH01: In the

skeletonbow: This brings up an interesting question to which I don't really expect to get an answer, but... I've been using a Hurricane Electric tunnelbroker.net IPv6 tunnel since 2008 to obtain IPv6 Internet access due to the lack of IPv6 support by Canadian ISPs. There is no VPN software involved, just the drivers that come with the OS (Linux) which set up a tunnel endpoint using the 6in4 IPv6 encapsulation to Hurricane's terminal server endpoint. In my case, the endpoint that it chose for me when I signed up is located in New York City, and as such geolocation services may detect my IP address as being in the United States either specifically in New York, or just as being owned by Hurricane Electric which is an American ISP.
At the moment GOG.com does not have a presence on the IPv6 Internet (that I've noticed), and so my traffic to GOG goes over IPv4 from Canada, however... in the probably near future when GOG does enable their services over IPv6, my browser, Galaxy, etc. will begin to connect to GOG for the first time over IPv6, routed through New York City visible as an American IP address.
When they do so, I hope there is a way to configure my account to indicate that my IPv6 IP address is in fact terminated within a Canadian household, or I may have problems purchasing from GOG as I do not intend to disable my IPv6 tunnel nor institute hacks or hassles to work around any geolocation problems that may arise.
I may be thinking overly-cautiously, but I've actually had this exact same problem at Bundlestars.com 2 years or so ago and it was a headache to even explain it to them let alone get them to sort it out. I just checked Bundlestars and it appears I'm accessing them over IPv4 so they may have disabled their IPv6 presence to prevent problems with dualstack customers and offload solving these issues to the future.
Hopefully GOG will postpone such upgrades until my ISP (Shaw Cable) provides native residential IPv6 support.
Just Skelzy predicting the future... :)
