for the x Xx program when a satellite crashes in Brazil, apparently killing them both.
Shortly afterwards, a team of four skilled individuals led by Xiang infiltrates the highly guarded CIA headquarters in order to retrieve "Pandora's Box", a device which is capable of controlling satellites to crash at specific locations as warheads.
In my network i have about 1000 targets and i use the Class C of address.
I personally would avoid 192.168 totally because it doesn't flow off the fingers like the low-hanging fruit in 10.x does.
On the other hand, if you have a site policy of avoiding 192.168, it makes it easy to use such addresses for local playing (ie VMware). We use the 10.1 subset but some client sites exposed within our intranet use 192.168, the result being that when I work from home I can resolve all domains but cannot access some sites without doing SSH-in-RDP.
As everyone has mentioned, there is no difference between them.
You can carve the address space as small or as large as you want.
I would avoid using the whole 10/8 at once because if your network ever grows beyond around 4000 systems the arp noise is going to start taking a non-trivial amount of bandwidth.
