 Machine:
 MacPRO 5,1 running High Sierra 10.13.6

 Loopback:
 MacPRO:~ johnhall$ ifconfig
 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
         options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>
         inet 127.0.0.1 netmask 0xff000000

         inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
         nd6 options=201<PERFORMNUD,DAD>

 localhost:
 MacPRO:~ johnhall$ head /etc/hosts
 ##
 # Host Database
 #
 # localhost is used to configure the loopback interface
 # when the system is booting.  Do not change this entry.
 ##
 127.0.0.1       localhost
 255.255.255.255 broadcasthost
 ::1             localhost

 Firewall in on in steath mode, but mtr returns the same result with
 stealth mode off.

 With stealth mode off I can ping localhost, but obviously not with it on.
