How to check DNS lookup in Linux?

I am using Ubuntu on Ubuntu 16.

04 Server. I don't have any GUI to verify the DNS lookup in my workstations and servers. I did check it through /etc/resolv.conf file. Here is the resolv.conf -
Generated by NetworkManager. Nameserver 4.2.1
Search mycompany. But I am interested to know if there is any command to see the DNS look up? DNS lookups do not normally go through /etc/resolv.conf because they are part of the dnsmasq process. The system uses dhclient to query for the ip-address of the router which can then be used to query the DNS server(s).

You can however easily monitor your LAN dns settings by using nmap. Simply running a scan will show you all the computers that have a working dns setup. A successful resolution from a hostname in this list will mean it's responding through dns. A "hostname not found" will mean it isn't, since nmap will just return a port unreachable message.

How to see DNS records in Linux command?

Is there any way to see DNS records in Linux?

I'm on an Ubuntu 12.04 machine.

I've already looked at /etc/resolv.conf but I don't think that's what I'm looking for.

Try this command: dig @8.8 yahoo.com
You might get a lot of info, and some of it is confusing. The most important part of the output is: ;; QUESTION SECTION: ;yahoo. IN A If you're looking for all records for a given domain, you'll need to look for A records, which can be easily done with this command: dig @8.com The output will then be something like this: ;; ANSWER SECTION: yahoo. 1499 IN A 173.194.36.29
