That's because host(1) doesn't look at the local hosts file. The third
line of the man page explains host this way:
"host - look up host names using domain server"
The bottom line: host(1) uses DNS only. Something as simple as ping is
generally good enough for testing weather or not the host name is
resolving correctly.
For example, my laptop that I'm sending this on now (aviion.alfred.cx)
is mapped in my hosts file as 150.101.93.190. Here's what happens when I
ping myself:
andrew@aviion andrew > ping aviion
PING aviion (150.101.93.190): 56 data bytes
ping: sendto: No route to host
(It's giving me "No route to host"'s because the port replicator for my
Portege isn't attached, giving the OS the impression its not there).
Basically, the thing to look for in the example above is the fact that
ping(8) resolved the name to the IP address as listed in /etc/hosts.
On your machine, processes (such as httpd, smptd, etc.) that do host
lookups are probably working the way you want them to already, you just
don't realise that because of your flawed testing methods.
