Code:
for IPADDRESS in 10.0.0.5 192.168.2.5 127.0.0.1; do
  ping -c 1 ${IPADDRESS} >/dev/null 2>&1
  RESULT=$?   
  if [ ${RESULT} -eq 0 ]; then
    echo "INFO: Server ${IPADDRESS} is okay."
  else
    echo "WARNING: Server ${IPADDRESS} is NOT okay."
  fi
done

Result of running the above:
WARNING: Server 10.0.0.5 is NOT okay.
WARNING: Server 192.168.2.5 is NOT okay.
INFO: Server 127.0.0.1 is okay.

check-hostname

check-hostname(1M)					  System Administration Commands					check-hostname(1M)

NAME

       check-hostname - check if sendmail can determine the system's fully-qualified host name

SYNOPSIS

	/usr/sbin/check-hostname

DESCRIPTION

       The  check-hostname  script  is a migration aid for sendmail(1M). This script tries to determine the local host's fully-qualified host name
       (FQHN) in a manner similar to sendmail(1M). If check-hostname is able to determine the FQHN of the local host, it reports  success.  Other-
       wise, check-hostname reports how to reconfigure the system so that the FQHN can be properly determined.

       /etc/hosts	     Host name database

       /etc/nsswitch.conf    Name service switch configuration file

       /etc/resolv.conf      Configuration file for name server routines
