I am testing IP blacklists through the botnet filter.
If I try to add:
62.5.128.0/17
to the blacklist - I get the error message 'The netmask is not valid'. Can anyone explain that? I mean, that is a valid netmask is it not?

That is correct.
What command are you trying to add?
dynamic-filter blacklist
I just tried to add it and it worked:
5505(config)# sh run dynamic-filter
dynamic-filter blacklist
address 62.5.128.0 255.255.128.0
check command reference here:

Perhaps it is a problem with the ASDM interface. I will try to connect directly and see if the command line is better.
