Installing dig on a CentOS or Red Hat machine

Gone are the days where we install nslookup for DNS resolution testing, the new(ish) kid on the block is dig. Although maybe not installed by default, it can be installed quite easily from yum, however it comes bundled with a number of tools so the package name isn’t all that obvious.

[root@server ~]# yum install bind-utils

Will do the trick, now how to use it?

[root@server ~]# dig @nameserver address.com

replace nameserver with your dns nameserver of choice, for example:

[root@server ~]# dig @8.8.8.8 google.com

will use Googles DNS server to resolve google.com
