[pmwiki-users] blocklist question - ip addresses

[adam overton]

hi
a quick question about blocklist and spam

in order to block ip addresses, is the format:
block:194.44.171.14
or is it it simply
194.44.171.14
?

i've been doing it with the block:ip.add.res.s and i'm not sure if  
it's working correctly

plus, does it only work if the ip address is in the form of
a.b.c.d or a.b.c.*

or is it also supposed to work if you only do
a.b.*

i've been doing this:
block:194.44.*

... and i'm still getting spam from various 194.44... ip's.
thanks for the advice
adam
