i want allow ip addresses between 145.050.039.008 , 145.050.039.017 inclusive for example (but doesn't work): allow 145.050.039.008 145.050.039.017 or: allow 145.050.039.008,145.050.039.017 or: allow 145.050.039.008/017 ? thanks, jelmar allow 145.050.039.008 145.050.039.017 check here details. (late) edit: my bad, previous answer never worked, @ time answered without understanding problem. option #1: define ip here's way it: allow 145.50.39.8 allow 145.50.39.9 allow 145.50.39.10 allow 145.50.39.11 allow 145.50.39.12 allow 145.50.39.13 allow 145.50.39.14 allow 145.50.39.15 allow 145.50.39.16 allow 145.50.39.17 option #2: use partial ip if want more generic, can use partial ip: allow 145.50.39 but allow ip 145.50.39.0 145.50.39.255 . option #3: use netmask or cidr to closer, can use netmask or cidr: allow 145.50.39.0/255.255.255.224 or allow 145.50.39.0/27 this allow ip 145.50.39.0 145.50.39.31 .

i have write ftp (auth tsl) framework in c#. i'm noob @ writing frameworks. e.g. when prove file exists , doesn't, should do? throwing exception programmer uses framwork? printing exceptionmessage (console.writeline()) without throwing exception? what professional in case? broad question actually, there clues on way: never use console.writeline() or stuff in framework. for methods framework.fileexists , if file doesn't exist, return false value. that's true nature of boolean return value. that's more semantic. for operations encounter problems, throw custom, or predefined exception. example, if need argument , want sure no null has been passed method, check argument in method's body , if it's null, throw argumentnullexception .
