I'm using linux (openSUSE 13.2) on my computer and my router is DD-WRT. There is a domain that, when I ping, keeps returning the wrong IP address.

My Router has the domain name server as Google's 8.8.8.8.

When I checked the domain there, it shows the correct IP (but ping shows the old one):

#this returns the CORRECT IP
nslookup thewebsite.com 8.8.8.8

On my computer, I ran:

sudo service nscd restart

On the router (via the web interface), I ran:

stopservice dnsmasq
startservice dnsmasq

Despite all that, I keep getting the wrong IP from ping. How do I figure out what's caching it and clear it?

    rather than worry about how the cache is managed for now, reboot the router, then test. reboot the client and test. if its still a problem, reboot both devices before testing. Once you have the device isolated, you can look into what software is responsible and the procedure necessary to flush the cache.

    @FrankThomas I discovered the issue. KDE has a cache application that's turned on by default (that i'd never heard of) and turning it off fixed the issue

Reset to default

After executing sudo service nscd restart --> stopservice dnsmasq --> startservice dnsmasq please try ifconfig eth0 down and ifconfig eth0 up. This is make the eth0 disable and re-enable. I had the same issue few years back and I got this working after re-enabling the interface.

Please make sure to enter the right eth number, in my case it was eth0. Let me know if you have any questions.
