nslookup and dig cannot resolve IP address from /etc/hosts since it was not design that way. There is a workaround that can help resolve entries in /etc/hosts.

You may need an account with Red Hat to access the following link:

Steps:

Install DNSMASQ
Code: Select all
```
# yum install dnsmasq -y
```
Edit /etc/resolve.conf to add the following line lookup the localhost
Code: Select all
```
nameserver 127.0.0.1
```

Add the following lines in /etc/dnsmasq.conf

Code: Select all

domain-needed
bogus-priv
filterwin2k
resolv-file=/etc/resolv.external
expand-hosts
domain=example.com
log-queries
log-facility=/var/log/dnsmasq
conf-dir=/etc/dnsmasq.d

Make a file for to specify external DNS server
Code: Select all
```
cp /etc/resolv.conf /etc/resolv.external
```
Put the entry of your entries not in DNS into /etc/hosts
Code: Select all
```
1.1.1.1    test.xyz.com
```
Start DNSMASQ Service
Code: Select all
```
# service dnsmasq start
```

check the results

Code: Select all

# nslookup test.xyz.com
Server:          127.0.0.1
Address:     127.0.0.1#53

Name:     test.xyz.com
Address: 1.1.1.1

NOTICE: Whenevera new entry is added to /etc/hosts, the dnsmasq service needs to be restarted to take effect.

Code: Select all

# service dnsmasq restart
Shutting down dnsmasq:                                     [  OK  ]
Starting dnsmasq:                                          [  OK  ]
