[QUOTE=Coffee;37667798]Data is sent in packets of electrical signals. This is sent in the form of bytes (8 bits). Because of 8 bits being the standard, in binary the highest number you can have is 11111111 (255), this is why you can't have numbers in the IPV4 system higher than the limit of 255.[/QUOTE] Ah, I knew there was a technical limitation but I thought we'd gotten over it by now. oh well I tried.
[QUOTE=lavacano;37667749]How about explaining what's wrong with the idea instead of just "lol ur stupid" I can't learn if nobody teaches.[/QUOTE] The reason it goes to 255 is because it uses 8 bits per each number, total of 32 bits. This is how ip 250.75.75.12 actually looks like and is saved like: 11111010010010110100101100001100 The lenght is set since it's a standard protocol and there's hundreds of thousands of devices and if we use IPv4 protocol, the devices expect the addresses to be 32 bits. The reason why it's written with 4 numbers is mostly convenience and easy cutting into pieces (at least it was at the start)
[QUOTE=lavacano;37667837]Ah, I knew there was a technical limitation but I thought we'd gotten over it by now. oh well I tried.[/QUOTE] Well there is a way to have many more IP addresses, IPV6, which uses hex (0123456789adcdef) which allows for up to 2^128 addresses.
We're running out of internets people.
[QUOTE=lavacano;37667749]How about explaining what's wrong with the idea instead of just "lol ur stupid" I can't learn if nobody teaches.[/QUOTE] Computers don't count in decimal, they count in binary, each byte (eight bits) in the address goes from 00000000 or 0 to 11111111 or 255, giving 256 combinations in each byte, IPv4 addresses are 32bits, so they're written down as 00000000 11111111 00000000 11111111 or 0.255.0.255 999 is 1111100111 in binary, that's not eight bits, it doesn't fit, it wont work.
Obligatory joke: IPv4: Doctor, I need to know what's wrong with me! Doc: What seems to be the problem? IPv4: It hurts when IP.
[QUOTE=trotskygrad;37664107]well this was going to happen sometime... watch us run out of IPv6 in 50 years or so[/QUOTE] Unless world population increases 10000 fold and every single person (even in poor third world countries) has a [highlight]quadrillion[/highlight] smartphones all connected to the internet at the same time this won't be a problem. [editline]14th September 2012[/editline] [QUOTE=maurits150;37667319]IPv6 will run out too, not because there aren't any addresses available, but because they give every person 1 trillion addresses. Stupid as fuck if you ask me and it makes banning by IP address a lot harder.[/QUOTE] Yea, it won't take long until there are 3.40282366920938463463374607431768211456 × 10^26 humans having 1 trillion IPv6 addresses.
Sarah Mclachlan needs to make an advert that is a slide show of sad and homeless IT people. "A just 1 IP address a month, you can put a IT professional back to work. We will even send a picture and information of the IT member you are supporting." [IMG]http://i.imgur.com/DWT5b.jpg[/IMG]
[QUOTE=Amiga OS;37668430]I like IPv4 though, the addresses are so easy to remember :saddowns:[/QUOTE] You won't have to remember your address with ipv6.
[QUOTE=Amiga OS;37668430]I like IPv4 though, the addresses are so easy to remember :saddowns:[/QUOTE] IPv6 isn't too hard to remember honestly. Plus there would be enough address to stick a domain on anything you actually wanted to access.
