Meaning

If the reply comes from your own IP, ARP failed on the local network. If it comes from a router, the route to the destination is missing or the next hop is down. Check the gateway, routing table and the target's subnet.

Common causes

  • Target host off or on another subnet
  • Wrong default gateway
  • Missing route on a router
  • ARP failed on the local segment
  • Firewall rejecting with ICMP unreachable

⚡ Quick fix

  1. Check ip route / route print for the destination
  2. Ping the default gateway first
  3. Run traceroute to find where it stops

Detailed fix by platform

Windows

  1. powershell

How to diagnose

  1. Reply from — Your IP or a router?
  2. Gateway — Reachable?
  3. Route — Present?
