Where can I find the DNS cache?

  • 772

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.

dns 12.04

  1. 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!

  2. Other options to dig command:

    dig soa host.tld

dig mx host.tld

    For manual page of dig, follow this LINK.

  3. Not sure if you're asking about a tutorial or something like the hosts file in Windows. I'm a part time Windows user too. In Ubuntu, the file's under /etc/hosts. To edit:

    sudo nano /etc/hosts
