Search Appliance
Syntax: one or more IP address prefixes separated by space or line break
Allow walk to fetch pages from any host within the network specified by the numeric IP address(es).
e.g.:
Given a base URL of http://www.example.com/ and extra network
192.0.2 the Search Appliance will walk all of www.example.com
and any URLs referring to any machine having an IP address prefix
matching 192.0.2.
Note: This option does NOT direct the walk to completely index every web server in the specified network. It simply allows walking them if a reference to them is encountered.
Note: Using this option has the potential to slow the walk, because every URL's hostname must be looked up. If there are many different off-site hosts, or your DNS is slow, the walk may be slowed substantially.
