Evan, you seem to be conflating the term "public ip" and "private ip".

The definitions as I understand them:

Public IP: The IP you present to the rest of the internet, for example, 
the ip address that an edge router at isp-x would see a packet as 
originating from when it arrives from your non isp-x connected origin 
system.

Private IP: An internal IP address used on a network separated from the 
public internet by routers performing network address translation, such 
that any computer external to that network sees all traffic from 
computers within that network as originating from a single public ip 
address, or possibly a small set of public ip addresses.

So a 192.168.x.x address would be a private IP address, not a public ip 
address. When bullis is in his hotel room in vegas with his blow up sheep 
and they're all using the hotel's wifi, they would normally all have 
private ips on the hotels private network, which through NAT would give 
them all the same public ip which I would see in my logs if they were 
accessing pictures of lolcats on my apache web server in the UK.

(Note - I don't actually have a collection of lolcat pics on my server!)
