IPv6 actually disabled or meerly inactive because there's no router advertisements on the LAN?
I suspect more of the second than the first. If it's just inactive, a compromised host can often broadcast a router advertisement or perhaps use local net addresses to compromise other hosts. A well prepared network would block ipv6 traffic on their switches, it they don't want it, but that's a big investment in capable switches.

- dogsledsleddog 2y agoWhich says: > You cannot completely disable IPv6 as IPv6 is used internally on the system for many TCPIP tasks. For example, you will still be able to run ping ::1 after configuring this setting. I'd be concerned their workaround is just limiting it into a local vulnerability that spyware, etc will abuse on all the systems that end up not patched because they used the workaround..
- GoblinSlayer 2y agoWhen spyware holds your ass, it already has everything on you and doesn't need any vulnerability.

- yyyk 2y agoI mean 'disabled in network adapter connection properties'. If you're already using IPv4 there's no reason for the extra complications of leaving IPv6 enabled.
- sgjohnson 2y ago> If you're already using IPv4 there's no reason for the extra complications of leaving IPv6 enabled. That’s just flat out wrong. No pure IPv6 deployments exist on endpoints in practice. Only in internal networks. You either run pure v4, or dual stacked v4+v6. IPv6 is gaining some pretty solid adoption these days, but it’s not there yet. Disabling it is holding back the deployment of it, and is a problem by itself.
- yyyk 2y agoThe context ('business LAN or industrial machine') referred to internal networks. What happened there doesn't really effect IPv6 adoption.
