Hello , Please can anyone explain me the exact Difference Between Request Timed out message and Destination host unreachable .
Request timed out means that the host received no response to it's query. Destination host unreachable means that a hop along the way replied that there was no valid route to the address supplied.
"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. "Destination Host unreachable" The browser couldn't even get to the server. This is usually a DNS problem. Domain Name Servers translate the name of a web site (what you type in the address field) to the specific physical server where it is located. It does this by matching the name to an IP (specific server address) address it keeps in a database. If something goes wrong with the DNS, this translation won't happen and you won't get to the site.
