Alex,

Most probably a bug in your Free CPE (that appears to be over-zealous)

Subject: [v6ops] out-of-focus: why DHCPv6 breaks Android computers?


This message is out of focus of current discussions.

Why the presence of a DHCPv6 server breaks Android computers?

On my CPE at home, of ISP Free, I noticed recently this message: 'Watch out: if you activate the DHCPv6 server, certain Android computers are at risk of loosing their IPv6 connection'.

Why and how the presence of a DHCPv6 server on the CPE breaks Android computers?

I would like to try this DHCPv6 server to connect my Windows 2-in-1 computer to work at home, but I dont want to break the other Android tablet that shows the weather report.

Alex
