The newer internet addresses, guarded the same as the old ones
The world ran out of old-style IP addresses, so most internet providers now hand out IPv6 too. Firecradle sets it up for you — and blocks it by default, the same as everything else, so it never becomes the door nobody remembered to lock.
Why IPv6 exists, and how Firecradle handles it
IPv4 addresses ran out years ago. IPv6 is the much larger replacement, and it needs to be set up and protected, not just switched on.
The most common IPv6 mistake
A firewall that carefully blocks IPv4 but leaves IPv6 wide open is not rare. It happens because IPv6 gets switched on quietly, and nobody writes rules for it.
Firecradle treats IPv6 exactly like IPv4 from the start. Default deny applies to both. A device does not get reachable from the internet just because it picked up an IPv6 address nobody noticed. Rules, logs, and reports cover both address types on the same screen, so there is no second firewall to remember.
What it runs on
How people actually use this
A firewall that only guards half the front door
The problem: An office locks down every IPv4 port carefully, but nobody thought about IPv6. Devices with a public IPv6 address sit wide open to the internet.
A new internet provider only gives an IPv6 line
The problem: A branch office is moved to a connection that hands out IPv6 addresses instead of the usual IPv4 ones, and none of the office equipment has been tested on it.

Common questions
Do I need to turn IPv6 on, or does it just appear?
Most internet providers now hand out an IPv6 connection alongside your regular one. Firecradle can pick it up automatically, but you stay in control of whether it is turned on.
If I do not use IPv6 on purpose, can it still be a risk?
Yes, and this is the biggest IPv6 mistake. Many devices turn on IPv6 by default even if nobody set it up. Firecradle blocks IPv6 traffic by default, the same as IPv4, so an unused IPv6 line is not an open door.
What is the difference between SLAAC and DHCPv6?
SLAAC lets a device build its own address with no server involved. DHCPv6 hands addresses out from a central point instead, which suits networks where you want a record of which device has which address.
Will my existing firewall rules keep working once IPv6 is on?
Yes. Firecradle manages IPv4 and IPv6 rules from the same screen, and a default-deny stance applies to both from the start, so IPv6 never quietly bypasses rules you already trust.
