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.

pmhostname
PMHOSTNAME(1) General Commands Manual PMHOSTNAME(1)NAME
pmhostname - report hostname
SYNOPSIS
$PCP_BINADM_DIR/pmhostname [hostname]
DESCRIPTION
pmhostname reports the name of the host hostname as returned by gethostbyname(3N).
If hostname is not specified, then the local host name is retrieved using gethostname(2) and this is than passed to gethostbyname(3N).
pmhostname provides a service for shell scripts that mimics the logic formerly used by Performance Co-Pilot applications when trying to
determine the official name of a host. PCP applications no longer use DNS-based heuristics, and therefore this command is deprecated.
If gethostbyname(3N) fails, the input host name (either hostname or the result from calling gethostname(2)) is reported.
PCP ENVIRONMENT
Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the
file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura-
tion file, as described in pcp.conf(5).
