(Was your reply misplaced?)

Your comment is wrong, but your code works: 

# USAGE: $masterhash{$ipaddress} = @aliases

That's the same as: 
$masterhash{$ipaddress} = scalar @aliases

[download]
What you want in this case is: 
$masterhash{$ipaddress} = \@aliases

The only justification for array of hashes I can come up with is if the number of entries is very large, and you manage duplicate hosts. (For example, the file is already sorted by host, and you keep track of the last host. If the current host is the same, the new data is added to the last host entry. Otherwise, a new host entry is created first.) But searching the host array to find the correct entry on a large array is problematic.
