The value of the object tmnxLudbHostUseGiAddress specifies
whether the GI address is used to search for an IP address for this
host.
If the value of this object is set to 'true(1)', then the Gateway IP
address is used.
This object can only be set to 'true(1)' when the value of
tmnxLudbHostAddrType is 'unknown(0)' and tmnxLudbHostPool
contains the empty string.
