playback security - Include client Ip in hash generation -want to exclude last digit

Wowza Streaming Engine
1

Hi,

I use wowza secure token v2 + include client ip in hash generation.

Seem work well but some of our mobile internet user said they have a error and stream didn’t load.

I check the log and their last ip digit mismatch with wowza generate ip digit .
Eg . Client Ip - 1.47.65.156 - wowza hash ip - 1.47.65.130
Not always happen , but often for mobile internet user.
So, I want to exclude last digit in hash generation and if first three digits are same , wowza session will allow to connect that IP address.
