The list of IP Block 141 addresses presented is a very good example of such a Class B network. The first two numbers represent the individual network, say a college campus or a company LAN, while the last two designate a particular host on that network. However, just because block 141 is assigned to Class B networks in Germany, does not mean that the list of IP addresses in Hacker.txt are incorrect. A LAN network not connected to any other LAN can have any set of IP addresses it chooses. Indeed, the 128.X.X.X series is set aside for just such purposes. If the Area51 computers are networked, it would be, IMHO a very private network, with no outside connections. On a different note, military networks are connected together by a different backbone system knwon as milnet. It sorta parallels the Internet and is even connected to it in places, hence hostnames such as eglin.af.mil can be pinged from the Internet. All traffic in and out of milnet is passed through gateways, and most nets employ a firewall to keep out prying eyes. What do ya want to bet all traffic through a gateway is logged? Anyway, the gateways and firewalls are capable of translating IP addresses from in to out and vice versa. This makes it practically impossible for a person on the Internet outside the gatewya to determine the actual physical address of the host on the other side. Hope this clears up a few points..... > The Lurker - "I Watch, I Listen" DC to Daylight! Xphile, Area51, Electromagnetic Phenomenon, Alternative Energy Sources, Black Project Researcher
