Try not using a tab. *shrug*

Forwarders
Any server can make use of forwarders. A forwarder is another server capable of
processing recursive queries that is willing to try resolving queries on behalf of
other systems. The forwarders command specifies forwarders by internet address as
follows:
forwarders 128.32.0.10 128.32.0.4
There are two main reasons for wanting to do so. First, some systems may not
have full network access and may be prevented from sending any IP packets into the
rest of the Internet and therefore must rely on a forwarder which does have access to
the full net. The second reason is that the forwarder sees a union of all queries as
they pass through its server and therefore it builds up a very rich cache of data
compared to the cache in a typical workstation name server. In effect, the forwarder
becomes a meta-cache that all hosts can benefit from, thereby reducing the total
number of queries from that site to the rest of the net.
The effect of ``forwarders'' is to prepend some fixed addresses to the list of
name servers to be tried for every query. Normally that list is made up only of
higher-authority servers discovered via NS record lookups for
the relevant domain. If the forwarders do not answer, then unless the slave
directive was given, the appropriate servers for the domains will be queried directly.
