Squid will not make any DNS lookups unless required by configuration.
Sources to DNS lookups on an firewalled Squid (never_direct allow all):
1. acl's using srcdomain, dst or dstdomain. (dstdomain calls for DNS if
seeing an IP address based URL)
2. log_fqdn on
3. any requests matching always_direct rules (bypasses never_direct).
4. Not starting Squid with the -D option. (-D disables initial DNS
checks done during startup)
