    <notes>The IPv6 Unicast space encompasses the entire IPv6 address range 
with the exception of ff00::/8, per <xref type="rfc" data="rfc4291"/>. IANA unicast address 
assignments are currently limited to the IPv6 unicast address 
range of 2000::/3. IANA assignments from this block are registered 
in <xref type="registry" data="ipv6-unicast-address-assignments"/>.
