Request Timed Out and Destination Host Unreachable

There is some confusion over the difference between the, "Request Timed Out" message response and the, "Destination Host Unreachable" message response.


"Request timed out" The browser reached the server where the web site is, made repeated requests for data but was ignored. Browsers set a time limit so when they reach a server that does not respond they will not get stuck forever. After a while they give up.

On the other hand, a "Destination Host Unreachable" message response indicates that the browser could not reach the server, such as when there is a problem with the DNS service. The server can't be found or there is a problem with the name to IP address translation.
