<p class="MsoNormal"><span style="font-size:11.0pt">Not sure if this is out of the scope of IPP PWG, but Apple AirPrint has requirements for support of IPv6 addressing that does not appear to be in any standards.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">For example, the following is an ?IPvFuture? IPv6 address (note the "v1." on the front):<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="p1">ipps://[v1.fd3f:7b2c:b134:364b::abcd]:443/.<o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Does it make sense that this format IPv6 address be required to be supported by a printer as this does not appear to be any part of an approved standard?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Also, there is the issue of Scope (or Zone?) ID's: the addition of "%X" on the end of an IPv6 address where X is a reference to the local client interface. According to what I read, the scope id is only relevant
for the local machine and helps identify which interface the client request goes out on, and it should be removed by the client before communicating on the network, so why would there be a requirement that a printer IPP or HTTP daemon/server comprehend IPv6
addresses with a scope id appended?<o:p></o:p></span></p>
