Which IOS or RouterOS has that command?

Now, if the list included RHCE....

As James said, certifications are pretty narrowly targeted instruments; knowing 
how to set up the cisco IOS featureset of the day or deal with all the things 
you need to get those certs does not in any way touch real-world DNS issues.

At least if I were hiring someone, and they give me a list of certifications 
like the above, I wouldn't assume any knowledge past what the training 
materials of the week have in them; any other knowledge would be gravy.

You might be surprised how many network professionals have never had need to 
use whois or dig, and may not even know they exist, but be a whiz at MPLS, 
IPv6, QoS, etc things.
