If that is the case, gethostbyaddr() still won't help.  If an IP is
assigned, valid host information will still be returned regardless of
whether the IP came from DHCP or not, and that host information will not say
anything about where the IP came from.  Nick will have to query the OS for
the ethernet card's actual properties and see if a DHCP server is assigned
to the card or not.  He can use GetAdpatersInfo() for that:

    GetAdaptersInfo()
    http://msdn.microsoft.com/library/en-us/iphlp/iphlp/getadaptersinfo.asp

The IP_ADAPTER_INFO structure has DhcpEnabled and DhcpServer members
available.
