I recently downloaded bitcoin from github and changed the settings to allow for rpc.

This is how I have it:


This does not work anymore.

However when running bitcoind, it complains that:

Error: Invalid -rpcallowip subnet specification: 192.168.0.*.
Valid are a single IP, a network/netmask or a network CIDR.

I'm not that familiar with networking.

Can someone tell me what a valid network/netmask or network/CIDR is for all addresses that could be in 192.168.0.*

You want to use That's CIDR notation for 192.168.0.*.
