Yes, you can fix the IP segment yourself if needed. The following is an example of the IP segment you mentioned:

1.If you want to fix the entire 192.168.x.x IP segment, you can add 192.168/16 to the whitelist. This will allow all IP addresses starting with 192.168 to access your account. This setting covers all IP addresses from 192.168.0.0 to 192.168.255.255.

2.If you only want to fix the IP segment of 192.168.0.x, you can add 192.168.0/24 to the whitelist. This will allow all IP addresses starting with 192.168.0 to access your account. This setting covers all IP addresses from 192.168.0.0 to 192.168.0.255.

3.If you want to fix only the specific IP address 192.168.0.1, you can add 192.168.0.1/32 to the whitelist. This will only allow the specific IP address 192.168.0.1 to access your account.

By adding the corresponding IP address segment to the whitelist, you can control access to specific IP addresses or IP address ranges.
