On Debian, I use pdnsd to handle a local name server serving an
imaginary domain (shadow.local) as well as getting real names from the
DNS.

The configuration file is pretty simple to edit: you describe each name
server like this

server {
	label = "root-servers";
	root_server=on;
        ip = 128.8.10.90
           , 192.203.230.10
           , 192.5.5.241
           , 192.112.36.4
           , 128.63.2.53
           , 192.36.148.17
           , 192.58.128.30
           , 193.0.14.129
           , 198.32.64.12
           , 202.12.27.33
           , 198.41.0.4
           , 192.228.79.201
           , 192.33.4.12;
	timeout = 5;
	uptest = query;
	interval = 30m;      # Test every half hour.
	ping_timeout = 300;  # 30 seconds.
	purge_cache = off;
	exclude = .shadow.local;
	policy = included;
	preset = off;
}

which pulls in the root nameservers, which I got from running dig:
