Alright, first game of GTM RISK is over. Who wants to join on another one?

Gigafrost, I already said most of these. Also, security is based on the application (7th) and presentation (6th) layer and not the network (3rd) layer.
Also, IPv6 is going to be 32 characters, hexadecimal, long.

Because the first IP address is 0.0.0.0 and the last one is 255.255.255.255. It's 256^4 or 2^32.

Another thing, if there aren't enough IP addresses, can't they just reclaim the ones that have become defunct? Say, if an IP address hasn't been used for a year, then it goes back into the pool of IP addresses and can be reassigned to something else, same as with mobile phone numbers. Well, most IPs are assigned by contract, so you can't just reclaim an IP from someone that bought them. Smartphones. I hate the damn things. Partly because everyone thinks they're cool if they have one, partly because they're responsible for some of the theoretical running out of IP addresses, but mostly because if you lose it, you are utterly screwed.
Way to generalize. EVERYONE that has a smartphone thinks they're cool? Does the usual businessman that uses a Blackberry to connect to their Exchange server think that they're awesome? No, it's just a tool, a pretty useful but dreaded terminal (since it makes you reachable everywhere all the time). Neither do I, owner of an iPhone, think that I'm cool. It's a work tool for me. I use it to browse the intertubez or to communicate with my clients when I'm not home or on the train (FYI: I do about 4 hours of transit every weekday). The IPv4 protocol should have been abandoned long ago. Blame residential ISPs for the fact that we still use it.

Of course I misspelled "patch" as "path".

to be on topic, now a lot of this mainly confuses me and sparkey was talking crap. but when the IPv6 would be used, how would an IP address then look? and if it works differently with just more numbers between the dots and letters inserted in it, then we wouldn't be able to play games online that can only use IPv4 addresses (if they are different like that).
Here's how an IPv6 address looks like: 2001:2f4e:1337:F34A:0000:0000:0000:0000It's quite long since it's 128-bit. You can omit the zeros, so you get 2001:2f4e:1337:F34A::And no, it won't work with old games and software, get over it. You can always use tunneling. Also, IPv6 addresses have a huge advantage when it comes to subnetting. With IPv4, a network had an external IP address visible from the internet (let's say 56.134.27.76), and another local network, with computers having addresses from let's say 192.168.1.1 to 192.168.1.255. The problem is, you can't directly access the network from the outside, if not via port redirecting on the gateway (the machine that has both an internal and external IP address, that acts as a "bridge" between the two networks), like saying that port 22 accessed on the external address is being redirected to the machine with the internal IP 192.168.1.34, and port 80 is given to 192.168.1.46. Another option would be fiddling around with setting the destination IP on a packet sent from the outside network and sending it to the gateway, which might redirect it to a local computer if it's configured so. But unfortunately the sending computer can't be more than one hop away from the gateway. What IPv6 enables you to do is set the first half of the address as the address of the network, then the second part of the address as different addresses for each computer on your subnetwork. This allows direct access to the computers without assigning virtual ports. There are also several other advantages, like the simpler header, the fact that routers don't need to perform fragmentation, the IP layers doesn't have checksumming (done by higher layers like TCP), and TTL has now became Hop Limit.

I did'nt build THAT, but, the point is is that it can make a 10 digit number all on it's own by reading a card and I should get some credit for that.
So, what if it does come up with a number........Jonzu95 IS ALREADY USING IT on his phone!
You are not getting the point THE NUMBERS ARE ALL USED UP!

It doesn't work when it's called a "calculator" but it doesn't calculate anything. Good day sir.

I understand the mechanics. I don't understand the logic behind it, if there's any whatsoever.

As for me, I completely agree with Serge on the IPv4 matters. This isn't the end at all... until IPv6 runs out of addresses, but I have a feeling that they'll have a new system up well before they even get close to running out.
IPv6 is 128-bit. That's a lot. About 3.4e38. That's a 34 with 37 zeros. There's a bout 10^80 number of atoms in the universe. If you gave an IPv6 address to every second atom in the universe, it wouldn't run out. @Sparkey. I understood. I'm describing how the "cards" would look like. But the way you represent numbers make no sense whatsoever.

The crap you described won't add them, I already explained it to you.
1) you mix and match decimal and binary. what the sh**?
2) there's no carry
3) get out of here and learn about what you're talking about
It was'nt mixing binary, stupid. I was using binary to represent it. IRL is would be a car full of holes, representated by the friggin 0s.
So wait. Let's switch to 8-bit instead of 10-bit, because that's easier to use. Let's take the humble number 42. Its representation in binary is 00101010 in 8-bit little endian or 01010100 in arbitrary-sized big endian. So when you want to add a 42 to a 43 you put this on your card: 00101010 <- 42
00101010 <- 43The wheels start out at 0 0 0 0 0 0 0 0. After the first number they switch to 00101010. After the second number they switch to 00202021. Now please tell me, what the crap is this wankery, and where's my 85?

You can't "read" it. You're not storing it anywhere for computation. All you did was take a faw bars and translate holes to linear motion. I can build that sort of crap from Legos in a dozen of minutes.

here is a decription:
the thing will function on Ten lines that all go up to ten. You will take a punch card designed to run with it, and use a whole puncher to punch holes counting as numbers, shown below:
1111111110
1011111111
1011111111
0111111111
1111111111
1111111111
1111111111
1111111111
1111111111
1111111111
1 stands for paper, 0 stands for a hole. there will be a set of feeler Bars running through the card reader, that sit in place while the card moves along. Whenever one of the sensors on the feelers notice that
They've gone through a hole, it triggers a reaction to spin a servo that spins a number wheel, similar to that on a lock, that goes up to nine. there are ten of theese wheels, and as the card goes throught, each time
it feels a hole, the wheel adjecent to it spins up one number untill the card falls out the back, leaving you with a 10 diget number.
"will", "will". You said you built it. And this is way overkill. Servos? Spinning wheels? And this isn't adding, since there's no carry. You're also mixing binary and decimal. This is all bloody bullcrap. Now get off my lawn.

Meh.
If anyone wants me to type out a descrition of a working Punchcard calculator just to prove it I will.
Does it use strings? How much bits does it have (protip: each bit is two XOR gates, two AND gates and one OR gate, and that's only for adding)?
Ow, my head. I'd much rather use a PLC than have to deal with gates and gates.
Aren't PLC's glorified computers with multiplexed IO and higher temperature range? :P
