I completely agree.<br>
<br>
I get why line of business applications; e.g. billing,
provisioning, <br>
repair, haven't been updated to support IPv6.<br>
<br>
But I believe that any network equipment vendor that is (or
has been for <br>
the last 1-2 decades) selling /new/ equipment really has no
excuse for <br>
not IPv6 not having feature parity with IPv4.<br>

I've had similar lack of success with my municipal GPON
provider. At <br>
least the people answering support tickets know what IPv6 is
and know <br>
that it's on their future list without even being in planing /
testing <br>
phase.<br>
