Remember that ping often uses gethostbyname system/kernel call where traceroute often uses the actual DNS lookup. You can also easily test whether the entries are indeed in DNS by using nslookup or dig
Yes, ping (and traceroute) use gethostbyname() for resolving hostnames. And gethostbyname() goes to /etc/nsswitch.conf that must have the line
to consider first /etc/hosts then DNS.

nscd(8) System Manager's Manual nscd(8)NAME
/usr/sbin/nscd - name service cache daemon
DESCRIPTION
Nscd is a daemon that provides a cache for the most common name service requests. The default configuration file, /etc/nscd.conf, deter-
mines the behavior of the cache daemon. See nscd.conf(5).
Nscd provides cacheing for the passwd(5), group(5), and hosts(5) databases through standard libc interfaces, such as getpwnam(3), getp-
wuid(3), getgrnam(3), getgrgid(3), gethostbyname(3), and others. Each cache has a separate TTL (time-to-live) for its data; modifying the
local database (/etc/passwd, and so forth) causes the cache to become invalidated within fifteen seconds. Note that the shadow file is
specifically not cached. getspnam(3) calls remain uncached as a result.
OPTIONS --help will give you a list with all options and what they do.
NOTES
Nscd doesn't know anything about the underlaying protocols for a service. This also means, that if you change /etc/resolv.conf for DNS
queries, nscd will continue to use the old one if you have configured /etc/nsswitch.conf to use DNS for host lookups. In such a case, you
need to restart nscd.
