The nslookup, dig and ping return different values for me. I want foo.bar.name to always resolve statically to localhost on my machine.

I used the command host <myname.favorite.name> and edited

host foo.bar.name

and edited /etc/hosts to include the line 1.1.1.1 foo.bar.name foo 

1.1.1.1 foo.bar.name foo

(where 1.1.1.1 ip address of localhostmy host machine)

So that when I ping foo.bar.name it resolves to 1.1.1.1. LikewiseWhen I run either ping or curl locally to connect to foo.bar.name, it resolves to 1.1.1.1 and connects finebehaves the way I want. But

But when I run dig, andor nslookup for that matter, it connects to what must be some other source of DNS services and resolvesthe foo.bar.name to something else, not localhost. For a test I'd like to run, I need this machine to beaddress resolves completely oblivious to any DNS other than its own which should return localhost for foo.bar.name and no other ipsdifferently. What

Did I miss something?

What configurations do I need to modify to make sure that happen?on that particular host DNS resolution happens the way I've stated.

How to you override the default dns configuration in ubuntu so that nslookup returns static values?
