Well when I looked up $ignore, this is what I got.
$ignore(N/address)
Returns the Nth address in the ignore list.
Properties: type, secs
$ignore(0) returns the total number of addresses in the ignore list
$ignore(1) returns the 1st address in the ignore list
$ignore(2).type returns the ignore flags for the 2nd address in the ignore list
$ignore(2).secs returns number of seconds until ignore is removed if /ignore -uN was used
Note: If you specify an address, the first matching address in the ignore list is returned.
Now all you have to do is match the format of the mask you ignore.
Anyone else have any ideas? I really have no idea what he is talking about.
