Yes, you can pin a specific IP segment in the blacklist to block access to that IP segment. The following are instructions for expanding the IP range you mentioned:

1.If you want to fix the entire 192.168.x.x IP segment in the blacklist, you can add 192.168/16 to the blacklist. This will block all IP addresses starting with 192.168 from accessing your account. This setting can block all IP addresses from 192.168.0.0 to 192.168.255.255.

2.If you only want to fix the IP segment 192.168.0.x in the blacklist, you can add 192.168.0/24 to the blacklist. This will block all IP addresses starting with 192.168.0 from accessing your account. This setting can block all IP addresses from 192.168.0.0 to 192.168.0.255.

3.If you want to fix a specific IP address 192.168.0.1 in the blacklist, you can add 192.168.0.1/32 to the blacklist. This will only block the specific IP address 192.168.0.1 from accessing your account.

You can control access to specific IP addresses or IP address ranges by adding corresponding IP address segments to the blacklist.
