Hello Tony,

On Monday July 11 2016 10:24, you wrote to me:

Obviously I am not like you in that respect. ;-)

But it seems Joe is also an exception. He does not seem to have a SLAAC address...

Some of us use "hex speak" they have addresses withthe host part like like f1d0:1:280:5003.

I was a bit confused with "host par of the RFC 1918 IPv4 address"...

I see what you mean.

Yep. But why not just make it "25"?

Or use  2001:44b8:4176:f100::10.69.181.25.

The above is a legal IPv6 adress.


Can you guide Joe through the steps to configure a staic addy?



Cheers, Michiel
