Where can I find the DNS cache?

Question

I just want to see how IP addresses mapped to domain names in my local machine. Is it possible? Thanks.

BTW, it's just for fun.

Solution

You can try using dnsutils to do that exactly. They are not installed by default so here you go:

sudo apt-get install dnsutils

Then you can dig around the DNS System:

dig host.tld

Which will in return give you a DNS Record from your DNS Server specified in /etc/resolv.conf.

Caching is usually done by individual applications, like for example Firefox. To my knowledge there are only tools to flush the cache, not to read it out.

Cheers!
