Hi Kerry,
Yes, they can be derived from PIO. But is there any possibility
customers manually set subnet prefix?
Now, we disable SLAAC on the appliance (due to it provides important
services like web proxy/cache, web filtering, traffic monitoring) and
use the 3 parameters to configure IPv6 address
THanks Kerry and Brian,
Now we provide 3 parameters to our customers to configure a IPv6
address manually: 128bit address, subnet prefix and default gateway
(optional, if it is provided, it should be within the same subnet with
the 128bit address). Should we set subnet prefix to a fixed value 64

Brian, you're quite right. I had in mind only one particular class of IID.
Washam, see Appendix A of RFC 4291 regarding modified EUI-64 IIDs
with "u"=0. Also, RFC 3041 has been obsoleted; see RFC 4941 and
its errata if privacy issues apply in your situation.

The authors of RFC 4291 chose not to use the upper case normative
keyword convention defined in RFC 2119. Therefore, 'required' means
what in means in plain English (i.e. REQUIRED in RFC2119ish).

See also section 2.5.4 of RFC 4291:
"All Global Unicast addresses other than those that start with binary
000 have a 64-bit interface ID field (i.e., n + m = 64), formatted as
described in Section 2.5.1."
So I'd say the answer is the IID MUST be 64 bits long, and MUST
satisfy the properties of u
Hi,
I quoted this paragraph from RFC4291:
For all unicast addresses, except those that start with the binary
value 000, Interface IDs are required to be 64 bits long and to be
constructed in Modified EUI-64 format.
But I am not sure how to interpret the text in a correct way.
If I ass
