Hosts file questions - format, duplicates, IP addresses

Does it matter if the space between 127.0.0.1 and the
domain name is a tab, or must it be a space?
Do duplicate entries cause any problems.
What's the difference between:
127.0.0.1   example.com
127.0.0.1   *.example.com
127.0.0.1   www.example.com
Wouldn't the first one take care of all three?
Can IP address ranges be used?
127.0.0.1   123.123.123.*
127.0.0.1   123.123.*.*

In a txt file a tab is just a number of spaces, so no it does'nt matter

Each of the is treated seperately.

You cannot use wildcards such as ? or *

Doesn't matter.

1 is OK
2 won't work
3 is OK but is different than 1
