i don't know, we get the odd message from someone who has discovered
that some clients do a DHCPINFORM after they are already bound...they
did DISCOVER and REQUEST and are adddressed and everything, but elect
to DHCPINFORM anyway.  like the config they got wasn't good enough or

in this case, we find that these odd little clients will update their
nameservers if a different answer comes than was in the DORA exchange.

so it might actually be useful to just ignore the little buggers
without having to become non-authoritative.
