host/nslookup resolve dns queries directly using nameservers. They do not use /etc/hosts. If you want to resolve hostnames from /etc/hosts then you need to use getent:

Code: Select all

getent hosts ns1.lgichn.com

I think host command can get the IP address of an hostname from /etc/hosts file.

I have been using the same method on CentOS 6 without using any DNS to resolve hostname to IP.

Centos 6 should behave in exactly the same way as Centos 7 as regards the host command, it is a DNS lookup. If it works for this local hostname on a particular system I would hazard a guess that the system is set up as a nameserver, host and nslookup do not work with local /etc/hosts files. Check the man pages to confirm this:

HOST(1) BIND9 HOST(1)

NAME
host - DNS lookup utility
