The 10.xxx.xxx.xxx are private addresses and should never be seen on the internet. Another word for private could be 'internal'. In other words, it is an address on an internal network not a public IP address which is used to access the internet.
If a 10.xxx.xxx.xxx IP address is showing in Who's Online, then the IP address is being spoofed.
Unless you are accessing your site on an internal network with an IP that starts with 10, you can safely add '10.' (10 dot - without the quotes) to the Banned IP Addresses in vBulletin's User Banning Options. That should prevent the user from seeing any part of your board.
The same holds true for 192.168. addresses.
