Though when your domains are related like that, it's easier to just use
the 'domain' keyword:
domain sfbay.sun.com
or
domain i.mcintyreweb.com
Because those will cause dns to try the listed domain, and then
repeatedly remove the leftmost subdomain, and retry until there are only
2 parts left. For example:
domain a.b.c.d.foo.com
will search for 'host' in this order:
host.a.b.c.d.foo.com
host.b.c.d.foo.com
host.c.d.foo.com
host.d.foo.com
host.foo.com
'search' is useful when your domains to search aren't related at all,
like a.b.foo.com, and d.e.bar.org
