Hi, That's was not much a debate on doing dual stack on the same VLAN (we already do that), but to be able to put the IPv6 interface on a dedicated subnet for this kind of purpose, when you won't do that in your IPv4 network. I prefer to think where would be the right place for a thing in an IPv6 network rather than planning a network only on the IPv4 constraints. We can all do our IPv6 subnetting based on what we have done in IPv4, but that would mostly be a bad idea.

This is common deployment way - dual stack. And you don't waste IPv4 in this case. Regards. /Alex Saroyan On 02/26/2014 05:54 PM, Guillaume Sachot wrote:
You don't have a "guest" VLAN for "here any visitor can plug in their laptop, and have internet-only (no internal services whatsoever) IPv4+IPv6 access"? The guest network is WiFi based.
Also having IPv4 and IPv6 in separate VLANs seems like a sign that whoever did the v6 deployment had little idea of wtf they are even doing. I wonder if many people have such a wretched configuration that it would warrant adding the whole VLAN option to the interface. That's a bit presumptuous. Maybe the IPv6 VLAN is dedicated to this kind of external probes, and that we don't want to waste IPv4 by creating a dedicated one for the IPv4 counterpart when it can be put on an existing public range.

I also thought of that, but I cannot adapt a datacenter network only for one probe :) You don't have a "guest" VLAN for "here any visitor can plug in their laptop, and have internet-only (no internal services whatsoever) IPv4+IPv6 access"? Just place the probe into that same VLAN, it can't be trusted as it communicates with an external server and unconditionally accepts firmware upgrades from it anyway.
