<b>Name / Address field</b>\n
<p>\n
Here you can enter the host name or address.<br>\n
The host may be specified in a number of ways:\n
<p>\n
<i>single host</i>\n
<p>\n
This is the most common format. You may specify a host either by an
abbreviated name recognized by the resolver, the fully qualified domain
name, or an IP address.\n
</p>\n
\n
<i>netgroups</i>\n
<p>\n
NIS netgroups may be given as @group. Only the host part of each netgroup
members is consider in checking for membership. Empty host parts or those
containing a single dash (-) are ignored.\n
</p>\n
\n
<i>wildcards</i>\n
<p>\n
Machine names may contain the wildcard characters * and ?. This can be used
to make the exports file more compact; for instance, *.cs.foo.edu matches
all hosts in the domain cs.foo.edu. However, these wildcard characters do
not match the dots in a domain name, so the above pattern does not include
hosts such as a.b.cs.foo.edu.\n
</p>\n
\n
<i>IP networks</i>\n
<p>\n
You can also export directories to all hosts on an IP (sub-) network
simultaneously. This is done by specifying an IP address and netmask pair as
address/netmask where the netmask can be specified in dotted-decimal format,
or as a contiguous mask length (for example, either `/255.255.252.0' or
`/22' appended to the network base address result in identical subnetworks
with 10 bits of host).\n
