IMHO, every identifier ends up being routed, at least in some context.
If they are routed, they are not identifiers. They are locators.
An identifier simply names the object. It might enable connectivity
on a non-routed infrastructure, e.g., a local LAN, and if you want to
call this 'being routed', then your comment could be considered
accurate, but in a rather pointless sense.
For example, there is a good case that on a disconnected ad hoc
network,
it makes more sense to use the identifiers you have than to create
some
new addresses. Indeed, if one is willing to have individual host
entries
in a routing table, then one can use any identifier.
Then the locator and the identifier have the same value, but they are
semantically different.
I don't quite understand why this is so difficult for folks to
understand. IMHO, the failure to differentiate the two is probably
the biggest failing in the IP protocol.
