What does destination host unreachable mean?

Updated: 01/24/2018 by Computer Hope

Host errorThis message is typically encountered when running the ping, tracert, or other network command that is unable to communicate with the host you've entered. The following box contains two alternative versions of this same error:

Unable to resolve target system name computerhope.com

Ping request could not find host computerhope.com. Please check the name and try again.

Why am I getting this error?

These errors could be due to a network problem, a server being down, lack of certain privileges, firewall settings, misspelling, a bad Modem, router or router configuration.

Is the issue with my network or theirs?

If the host you are trying to access is on the Internet, enter the web address in the field below and see if our computers can connect. If our computers are unable to communicate with the host, it is likely that they are having issues with their network or server; it's not a problem on your end.


If our computers do not have an issue, or you are dealing with an internal network host, you need to diagnose the problem yourself. If you are not the administrator for this network, we suggest contacting that individual. If you are a home user, contact your ISP for additional assistance. If you are the network administrator, check your router settings, reboot the router, and run a traceroute to the host. If a traceroute cannot complete, one of the computers or routers between you and the host has problems.
