IPv4 to IPv6 switch - will the servers migrate?

well I don't know what ISP's in your contry do, but in Denmark each private ( corperate customer gets an uniq (mostly temperary) IPv4 IP when he goes online and that IP is recorded to belong to him until it's released (unless you have paid for a static IP). This has to be done this way so the ISP can prove who is accessing what on the internet. That means I can access any IPv4 IP on the internet directly.

If your ISP is making something affecting your access to the internet, then you will have to take it up with them. GGG's servers are running on IPv4 IP's and can be access by any IPv4 IPs.

As of now there is no reason for GGG to change to IPv6 regarding access to there systems.

It's definitely a western luxury to have your own public routable IPv4 address for a home router, even if it's from a DHCP pool. I have five public IPs and feel extremely guilty about it.

In many regions, particularly growing markets like Africa it's very common to have one or more levels of NAT at the ISP level already, so your home router gets a RFC private network address on the "WAN" side. People on those networks are totally screwed when it comes to port forwarding and are often blocked or rate-limited thanks to sharing upstream IPv4 addresses with others on their ISP. AT&T famously also did this in the US recently as well, putting everyone on 10.0.0.0/8 as a surprise.

The DS-lite approach that @Skomener describes sounds fun and is new to me, but has the downside of that IPv4 traffic is concentrated through a few v6->v4 gateways. IPv6 traffic in that kind of network is way more native and can be routed directly to the target. Once nice benefit is that it lets a vendor roll out native IPv6 internally while keeping IPv4 sources and destinations working, and it's a massive improvement over multi-level NAT.
