That's normal.

DESCRIPTION
 Host looks for information about Internet hosts.  It gets this informa-
 tion from a set of interconnected servers that are spread across the
 world.

Hi,

Command host does not check /etc/hosts file. Is it a bug or normal behavior?
My sendmail could not deliver mail to localhost. I had to comment the
following lines in the config file.

# Resolve map (to check if a host exists in check_mail)
#Kresolve host -aOKR -TTEMP
#C{ResOk}OKR

My system:

uname -a

I did some investigation:

Why does localhost resolve to 10.166.205.185?

localhost should always resolve to 127.0.0.1.  If it doesn't, something is
severely broken with your (or your ISP's) DNS setup.
