You want to know if the whitelist and blacklist of WFBS can recognize wildcard characters used in IP addresses.
Wildcards are supported and can be used when adding IP addresses to the whitelist or blacklist.
For example, the entry "http://61.220*" gives the following result in the TMProxy.log:
<TmpeURLf> Scan URL: "http://61.220.XXX.XX/" - UrlFilterEngine.cpp(228)
<TmpeURLf> Whitelist matched - UrlFilterEngine.cpp(277)
