	Don't use "localhost." as the nameserver as it will result
	in the root servers being queried for A/AAAA addresses
	unless you also have a "localhost." zone (the actual queries
	made are version dependent).

	Do use the name of the machine that is serving the data.
	This puts the load causes by additional data lookup where
	it rightly belongs.

	Do use a real contact address in case the entries leak and
	cause problems.

	Whan giving example use numbers rather than BIND specific
	extensions.
