I know this is not a security forum. I'm just trying to learn. I have seen a lot of screen shots here where the posters hide their internal network ip. Are there any security risks for exposing those ip addresses? I thought certain IP addresses are reserved for private networks, to be used on internal networks such as home networks. Examples of private ip addresses:10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255 and 192.168.0.0 to 192.168.255.255. Devices with private IP addresses cannot connect directly to the Internet. Likewise, computers outside the local network cannot connect directly to a device with a private IP. So what is the point of hiding internal IP address? Thanks.
