This is a problem I have reported twice now and it was already fixed 
once, but it was reintroduced by a recent change.

I suggest to drop using the old name attribute in favor of the new 
hostname attribute, which doesn't exhibit the problem, since it limits 
the checking to host names instead of host names and IP addresses.

I have changed all my host assignments without loosing anything, but 
gaining more reliability.

Generally speaking the name attribute is deprecated due to its universal 
matching ability.

The hostname and ip attributes allow for better reliability and get rid 
of many false matching problems.
