I just changed a host's ip addr from x.x.x.10 to x.x.x.20, and update it in win2k dns sv. All hosts / workstations are on domain.com. (same name suffix). There are no WINS settings. However on my sun host, `ping host` still goes to x.x.x.10, of course failed. `ping host.domain.com` is ok going to x.x.x.20. Q1: how to refresh sun T1's host-ip tables? I don't want to wait hours for them refreshing themselves, or maybe never unless reboot. Q2: on my sun T1, I `ping test-host`, it says alive, but how to find test-host's ip addr? arp does not help on both Q1 and Q2. Thanks for help from gping

To find out the IP and where it is getting the answer nslookup -debug test-host Look at /etc/hosts to see if it contains the old values

No entry in /etc/hosts at all. Is there any similar command in unix which equivant to WIN2k's ipconfig /flushdns or ipconfig /diaplaydns?
