20. ipAddressOrigin should be a TC (see item 15) 
    I prefer dhcp (v6 or v6 if need be) over some
    general string such as "assignedByServer" anyone 
    using bootp?
    I don't know what is "random" - 
    how does this differ from manual?

------------------------------------------------------------------------

Dave:

Random is very different from manual, and means the
system randomly generated the host id.
Two examples of addresses that use random today:
* RFC 3041 privacy addresses
* draft-ietf-zeroconf-ipv4-linklocal-02.txt autonet addresses

Bill:

The *Origin enums (ipAddressPrefixOrigin and ipAddressOrigin)
have purposefully different values -- routeradv is only valid
for a prefix, linklayer and random are only valid for addresses.
