ping and traceroute use gethostbyname to do the name lookup. While dig
and nslookup use DNS directly.

When using gethostbyname, it uses nsswitch.conf, host.conf or other
chooser to select which sources for DNS lookups to use and what order to
use.

Commonly your local file /etc/hosts is used first and then normal DNS
lookups is used if needed. Your normal DNS lookups are controlled by
/etc/resolv.conf.

So start by looking at /etc/hosts and then /etc/resolv.conf.
