From Harvesting to Scan - how long does it take?

It takes less than five seconds for your address to be harvested and scanned. The entire scan takes less than one second and scans over 100 common TCP and UDP ports.

How common is it to use the NTP?

Pretty much every computer these days sets it’s time to the atomic standard. Most often, a computer will use NTP to synchronize its clock to a public NTP server, as defined by the computer’s configuration.

What's IPv6?

Internet Protocol version 6 (IPv6) is the latest version of the network protocol that carries your data across your home or office network and across the internet as a whole. It's a very important upgrade for the internet and it will enable the unbounded growth of network connected devices that has continued to accelerate over the last two decades or more.

Randomized Addressing?

This refers to the so-called "privacy extensions" which provides a means for devices to assign themselves an IP address that is half home/network prefix and half random bits. This is supposed to offer a means to cloak the device by making its address nearly unguessable. but as we all know, security through obscurity is no security at all.

But temporary addresses are secure, right?

yes and no. They certainly help, and having a temporary, somewhat random IPv6 address that doesn't contain your MAC address is a step in the right direction, it's still possible to receive traffic on that temporary address, during its lifetime. Both devices had temporary addresses assigned. Both devices are behind a firewall and not used by users for internet communication.
