No matter which internal address you use, a Google search on what's my ip address or visiting whatismyip.com, whatismyipaddress.com or similar site will show 92.67.26.17 as your public IP v4 address.

I had three things in mind when I added that phrase:
- Changing the IP address can "smooth" traffic, potentially avoiding discovery by LAN traffic analyzers.
- Changing the address will "encourage" the NAT gateway to use a different outgoing port, again smooting traffic and potentially avoiding detection by ISP traffic analyzers.
- IPv6 goes directly through the local router, not using NAT. As such it is exposed to the internet, and depends on firewall packet inspection in the router and on the local machine for security. Changing the address could help avoid the firewall. It could also avoid global address tracking. DHCPv6 doesn't change this.
