Reproducible: Always Steps to Reproduce: The steps below are using the following lines within the hosts file on a W2k System. # This is mozilla ip address going to www.netscape.com #126.96.36.199 www.netscape.com # This is netscape ip address going to www.netscape.com #188.8.131.52 www.netscape.com 1 - uncomment the line with ip 184.108.40.206 and save the hosts file. 2 - go to url http://www.netscape.com (you should get the mozilla web site) 3 - now comment the line with ip 220.127.116.11 4 - uncomment the line with ip 18.104.22.168 and save the host file. 5 - hit reload on the url going to http://www.netscape.com Actual Results: You will still get the mozilla web page even if the ip for www.netscape.com is now pointing to the netscape site. Expected Results: Expected that the cache would notice that the ip for the host has changed then the cache would be void and it would reloaded from the new ip address. 1 - If I hit reload I would expect that the cache would be flushed. I beleive the media cache(html/gif...) is flushed however the ip address/domain is still cached. 2 - Even if I just continue browsing after step 5, it is still using the mozilla ip address for netscape.com domain. Now If I had not hit the reload then maybe I can see it still getting the ip from the cache. 3 - I can get it to work if I shutdown and restart the browser between step 2 and 5 4 - I checked this with other browsers - Netscape 4.8 and IE 6 SP1 and they behave the same way. 5 - you are probably wondering why would the ip address ever change? - We are developping a site using load balancing techniques where www.site.com can go to ip 22.214.171.124 and 126.96.36.199. - For us to do testing, we would like to connect to the 188.8.131.52 ip and 184.108.40.206 to make sure it works however if we go to www.site.com we get randomly thrown to one of these ip address. So we wanted to use the hosts file to make sure that we go directly to a specified box. Now we have to restart our browser every time we want to go to another box.
This is not cache.. (and it's a dup).

What is the dup - I can't find it.
We have an DNS (hostname->IP) cache. The records are currently permanent. I will dupe this when I have a chance to gather up all the bugs.
Summary: IP Cache not being flushed on reload → DNS: IP address do not refresh
