Checking host reachability on windows command line

How can I check in batch-file if host is reachable or not? The problem is that ping returns 0 not only on success, but also on Destination host unreachable error:

C:\>ping 192.168.1.1 -n 1

Pinging 192.168.1.1 with 32 bytes of data:
Reply from 192.168.1.1: bytes=32 time=3ms TTL=64

Ping statistics for 192.168.1.1:
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 3ms, Average = 3ms

C:\>echo %errorlevel%
0

C:\>ping 192.168.1.105 -n 1

Pinging 192.168.1.105 with 32 bytes of data:
Reply from 192.168.1.102: Destination host unreachable.

Ping statistics for 192.168.1.105:
    Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),

C:\>echo %errorlevel%
0

Is there any way to do it with ping or any other build-in-Windows tool? I would prefer not to install anything if that's possible...

Next code snippet should work:

set "_ip=localhost"
set "_ip=192.168.1.1"
ping %_ip% -n 1 -4 | find /i "TTL=">nul
if errorlevel 1 (
    echo ping %_ip% failure
) else ( 
    echo ping %_ip% success
)
  • -4 to force using IPv4 (as e.g. ping localhost replies IPv6 with no TTL= output)
  • | find /i "TTL=" as find command raises errorlevel well
  • >nul to suppress undesired output
