There's absolutely _no_ good reason to do that if you're only facing the internet with a single IP on your router as a NAT gateway, except to make your life hell. Only thing that may be worth doing is parting ways with the one internet-facing IPv4 and relying solely on IPv6 there, but that's mostly up to your ISP and their own infrastructure. Even if you were to 100% NAT your IPv4 LAN to IPv6 WAN, and your ISP still dedicated your router a public IPv4, it'd benefit no one.
- BlueTemplar 3y agoWhy wouldn't you be able to disable IPv4 in the router ? Also, isn't trying to run both IPv4 and IPv6 inherently a security issue coming from the complexity of dealing with two overlapping networks with very different logic ?
- simiones 3y agoThen how would you reach the IPv4-only internet (i.e. a large part of the Internet)?
- crote 3y agoIt depends on your ISP, but providers are slowly switching to IPv6-only connections to their customers. The customer's router converts v4 to v6, and a translator at the ISP converts back to v4. If you do the 4-to-6 translation on your own machine, your local router doesn't need to know about v4 at all. This is already happening with mobile networks.
