Perhaps the host cache needs to be invalidated (nscd, sssd)? What OS and version are you using?
From man nscd of an old version of nscd for example:
Code:
NOTES
Nscd doesn't know anything about the underlaying protocols for a ser-
vice. This also means, that if you change /etc/resolv.conf for DNS
queries, nscd will continue to use the old one if you have configured
/etc/nsswitch.conf to use DNS for host lookups. In such a case, you
need to restart nscd.
Newer version of nscd try to watch for changes to this file, but even then there may be a delay..
NOTES
The daemon will try to watch for changes in configuration files appropriate for each data-
base (e.g., /etc/passwd for the passwd database or /etc/hosts and /etc/resolv.conf for the
hosts database), and flush the cache when these are changed. However, this will happen
only after a short delay (unless the inotify(7) mechanism is available and glibc 2.9 or
later is available), and this auto-detection does not cover configuration files required
by nonstandard NSS modules, if any are specified in /etc/nsswitch.conf. In that case, you
need to run the following command after changing the configuration file of the database so
that nscd invalidates its cache:
$ nscd -i <database>
I don't have DNS, and would like to resolve EVERYTHING through local /etc/hosts file.
My first sunbox has the following configuration:
# hostname
mybox.home.com
My host file is as follows:
# cat /etc/hosts
#
# Internet host table
#
127.0.0.1 localhost

nscd
NSCD(8) BSD System Manager's Manual NSCD(8)NAME
nscd -- name service caching daemon
SYNOPSIS
nscd [OPTION...]
DESCRIPTION
Nscd caches libc-issued requests to the Name Service. If retrieving NSS data is fairly expensive, nscd is able to speed up consecutive access
to the same data dramatically and increase overall system performance. Nscd should be run at boot time by /etc/init.d/nscd.
OPTIONS -d, --debug
Do not fork and display messages on the current tty.
-f, --config-file NAME
Read configuration data from NAME. For a description of the config file format, see nscd.conf(5).
-g, --statistic
Print current configuration statistics.
-i, --invalidate TABLE
Invalidate the specified TABLE, i. e. forget all data cached therein. This should be used if the database storing this information
has been changed.
-K, --shutdown
Quit a running nscd process.
-S, --secure TABLE
Use a separate cache for each user.
-t, --nthreads NUMBER
Start NUMBER threads. This denotes the maximum number of requests that can be handled simultaneously. The default is set in the con-
figuration file. (See nscd.conf(5).)
-?, --help
Print the list of available options.
--usage
Print a short usage message.
-V, --version
Print program version.
FILES
/etc/nscd.conf
Nscd configuration file. See nscd.conf(5) for more information.
/etc/nsswitch.conf
Name Service Switch configuration. See nsswitch.conf(5) for more information.
