Looks like my local server timed out waiting for the answer ...

>steve@example.com:~$ host -t any www.tokyostreethockey.com
>www.tokyostreethockey.com       A       202.238.0.248

but the answer came in shortly, and it returned what was in the cache.

still in the cache.

I tried what you typed, and got different responses:

	tokyostreethockey.com name server ns1.rainbow.co.jp

OK, this is what I got.  We evidently have different versions of host
(not surprising; there are three main commands, `host', `dig', and
`nameserver' and on many systems one or more is emulated by scripts
wrapped around one of the others).

	$ host -t any tokyostreethockey.com
	tokyostreethockey.com start of authority        www.tokyostreethockey.com

This is a typo; the -t flag requires an argument, one of A, NS, CNAME,
any, SOA, etc (types of DNS record).  You need to delete the -t as
well as its argument.  I actually made this typo, too, but I didn't
include it in my post :-)

    Dave> Is this something to worry about?

No.  The weirdness I got above could be (now that I think of it) a too 
short timeout somewhere on my end.
