user1@w2100z% telnet sys42.vceguide.com
sys42.vceguide.com: node name or service name not known
user1@w2100z% getent hosts sys42.vceguide.com
user1@w2100z% nslookup sys42.vceguide.com
Server: dns.vceguide.com
Address: 192.168.224.10#53
Name: sys42.vceguide.com
Address: 192.168.222.15
user1@w2100z% grep sys42 /etc/hosts
user1@w2100z%
