IPv6
 

This is going to take some getting used to.
My friend has an IP which is like:
3ffe:b80:d9:1:20a:95ff:fef5:d88f

It's in hex instead of 0-255 for each part which is going to be quite annoying in the future when reading out IPs over Teamspeak! :D
Does anyone use IPv6 in work etc?

I guess it will also make it tricky to know whether you're looking at a MAC or IP address :spin:

Re: IPv6
 

I did a 1 week course on it about two years ago, but not used it ever since. Despite what some say - we won't need to switch just yet - there are quite a few IPv4 address ranges still free, and with classless routing, we should be ok for a fair while yet. :) btw Greenkeeper - IPv6 addresses are much longer than mac addresses. :D

Re: IPv6
 

Hmm.. did some research into the number of addresses and came up with this:
IPv4
Over 109 (42 billion)
IPv6
Over 1038 (3.40E38개 ) = 43 billion * 43 billion * 43 billion * 43 billion

I can't see a future where we have more than 42 billion computers which need a public IP address. :confused:

Re: IPv6
 

Devices though? Not everything that needs an IP address is a computer...

Re: IPv6
 

think towards the time where everything is networked together...

for example, i know a guy who has a mad system setup in his house, ok so he still only has two public ip addresses, but you can see where techology might end up.

Everything (and i mean everything!) in house his house is networked.... for example, when he takes food out of his cupboard, he scans the barcode, and then does his cooking. when he has finished, he either scans the container as he puts it away again, or scans it on the barcode reader above the bin. The information is then sent to his database of what food he needs to buy, which is setup with rules as to what he needs to stock, how often, etc, and then this compiles a list which is sent to another pc to complete an online order with the supermarket. At the end of the week the order is setup, and the next day all of his shopping arrives. The bill from the online shop is then sent to his financial management software, and will automatically be deducted from his budget, and then this is checked against his online banking to make sure everything is correct.

The results are sent to his printer once a month and his bank statements from his own budgets, and also bank accounts are given to him... copies of course left on his server and he is alerted, via... wait for it... a flashing display in his lounge if there are any discrepancies.

Along side this he also has integrated burglar/ fire alarm systems/ cctv cameras, a coffee table which doubles as a multimedia pc, and much much more...!

If networking carries on in this way, every single device you can think of will be connected to some kind of network, and therefore need an ip address. 6 billion people in the world at the moment, so if they each had 7 public ip addresses, then they would all be used up! Bear in mind that the population is increasing... technology is becoming more popular etc, and i am sure that we will reach the 42blllion mark!

Re: IPv6
 

Don't forget mobile phones which need 2 IP addreses each, cars, train, buses etc, gaming devices, that 3D holographic communicator thing which we will have in 5 year time. Yep, IP6 should just about be enough.......

Re: IPv6
 

As already stated, in the future your fridge, washing machine etc., will have an IP address so you can communicate with them. So you can start your laundry before you even get home. :)

LG are doing something like this at the moment.

Re: IPv6
 

I think you've all missed something in the earlier calculation. The number of addresses available using IPv6 is not 42 billion but 42 billion * 42 billion * 42 billion * 42 billion.

The current IP addressing scheme uses 32 bits so, theoretically, it can have 2 ^ 32 = 4,294,967,296 addresses.

IPv6 uses 128 bits so it can have 2 ^ 128 = 3.4 * 10^38 addresses (3.4 followed by 38 zeroes).

I think that should be enough to be going on with! ;)

Re: IPv6
 

Think the 42 billion figure being used in examples was the IPV4 count not the IPV6 number which is the one you posted :)

Re: IPv6
 

Knowing next to nothing about mobiles, why do they need two IP address's?

Re: IPv6
 

True - but wont all these just be Dynamic Natted to one IP Public address?

EDIT: Unless you argue that there wont be any need to do this... ;)

Re: IPv6
 

If you don't NAT them then won't your fridge, washing machine etc all need to have firewalls, av etc, wouldn't want someone sending out the washing machine virus that sets all Bosch washing machines to do a 90deg Hot Wash and ruin your undies now would we (or perhaps your undies need a 90deg hot wash?).

One for calls and one for internet stuff.
