Lion “hosts” File Bug

Question

I have some serious problems with the hosts file on my Lion 10.7.2. My hosts file is like following;

127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost

27.0.0.1 first.localhost
::1 first.localhost
27.0.0.1 second.localhost
::1 second.localhost

I have more than 2 local sites but I just cut is short.

I can't manage http://first.localhost/ to work. http://second.localhost/ works fine but http://first.localhost/ doesn't work. If I delete the last two lines (which corresponds to second) than http://first.localhost/ works.

How can I add more than one local site in my hosts file? I'm using Lion 10.7.2 which I upgraded today and all those problems arose after that upgrade.

Note: There is nothing wrong with Apache config files or any other file with the local web server, I know that it's the /etc/hosts file that causes the problem.

Thanks.
