Distributor ID: Ubuntu
Description: Ubuntu 14.04.2 LTS
Release: 14.04
Codename: trusty
Expected: Returned FQDN and IP should be that of box sending ICMP
errors/replies.
Actual: Getting the FQDN and IP of an intermediate router, even though
replies are coming from another host.
Situation:
Pinged a remote box which was restarting. Initially got ICMP from the
intermediate router but when pings restarted the FQDN & IP are that of the
router, not the pinged host:

Setup:
1. Hosts "me" (x.y.2.60) and "edi" (x.y.1.131) connected via router (x.y.1.1
and x.y.2.1)
2. Disconnect or reboot remote box "edi"
3. Start ping.
4. Watch for ICMP Destination Host Unreachable from router
5. Connect (or wait for reboot to complete) remove box "edi".
6. Note that ICMP replies will start but show FQDN & IP of intermediate router,
not the pinged host.
Think the router FQDN is being cached and returned in error.
