Why does the aboave command prints URLs, Websites addresses that we have never accessed before ? When your system communicates with the DNS server for resolvingthe name queries, Your system builds the cache over the perios of time, This cache normally contains records from the host file and also the retrieved records from the recently resolved queries. Coming to the question that the site which were never accessed showing up there. DNS cache notes down positive and negative results as well. as you know caching is all about performance improvment. Now lets say you accessed Website1 and Website1 has some functionalities which makes it to communicate with Website2. Now Fortunately or unfortunately Website2 is blocked in your network and name query for this Website is not resolved. Still this unresolved queries will be recorded in DNS cache. I think those results are coming as they were initiated from your system implicitly. Issue this command to clean the DNS cache
