North America down to its last ~130,000 IPv4 addresses

Re: 2 things wrong with IPV6

@AC

(and letters beyond F, too).

the reason the letters go to F is because each digit is a Hexadecimal number (0-16) and expressed as a single character from 0-9 A-F

@ Charles 9

The Hexadecimal numbering system is used which is why you see numbers 0-9 followed by letters A - F

@ Preston Munchensonton

its your router dishing out IP addresses not your OS.

no there won't be an ipv7, it'll likely be called ipv10 but we need something beyond ipv6.

enterprise upgrades are not stopping ipv6, they are the ones for whom moving to IPv6 would be easiest as they control more readily ingress/egress and can easily put in ipv4 to ipv6 gateways at their borders. Many enterprises are running dual stack internally right now.

NAT is great for enterprises as they get to hide all their hosts behind a handful of public IP's, IPV6 can expose all their hosts addresses to the net.

There are many many issues with IPv6 that enterprises don't like but they are not holding up adoption.

Re: The market in operation

where do you get your facts from?

http://www.bbc.co.uk/news/technology-32826353

ISP Networks are layered by design with loads of expensive kit already balancing, proxying, billing, inspecting and securing traffic flows, if they needed to NAT its likely they have the kit and expertise already. I doubt so called carrier grade NAT will ever be deployed as its not needed especially with companies handing back addresses they don't need.

@ Bronek Kozicki Privacy

yes the randomness is in place but it's optional, who's to say its not possible to decrypt the obfuscated address?

We need IPv7 with IPv6's issues resolved before we see mass adoption of IPv6.

@AC,

it wasn't NAT that stopped IPv6.

There are fundamental issues with IPv6 which is why adoption is so slow. If it was somehow better than IPv4 everyone would have piled on it like all the other improved standards we use on the net (SSl->TLS, java, flash, xml etc).

MAC address privacy inches towards standardisation

Re: Randomising MAC address

filtering by MAC was convenient, but as you should know, MAC's sent on the wire/less can be changed to what ever you want. Need a better way to do the same task like NAC (802.11x)

Re: IPv6 addresses

@ Sebby

it is relevant.

1) if the ipv6 router assigns the IP with the MAC as the host part then all on the net will see what machine you are using, where you are using it, can check where you've used it in their system & compare against commercial lists from other organisations. Pop into M&S and your phone tries to connect to their wifi then visit their website when you get home they can then link your device & then likely your home network prefix too just for visiting their site, not even logging in.

2) If they have your MAC but don't use it in the host part of IPv6 they can track your visits and sell that info on.

please feel free to work out why that might not be such a good thing.

Smart meters set to cost Blighty as much as replacing Trident

chris 17
Bronze badge

I have a www.smappee.com which i very very rarely now look at. The rest of the household weren't really interested in it and aside from the initial flurry of seeing what consumes when & turning off (the shredder consumed 60 watts in standby) our habits haven't really changed. Typically, new appliances use less energy in use and standby and is where we would make the savings over time, swapping a CRT TV for a Plasma / CCFL LCD saves a lot, moving to an LED LCD saves even more & Switching-mode power supplies are much better than the old transformers.

Smart meters will not have any significant impact on reducing power usage. The cost of energy will do that.

Re: Or you could just...

Sky bangs on Ofcom's door – demands BT competition probe

chris 17
Bronze badge

OfCom should let Sky should merge with VM on the proviso that they build out the network to match BT's universal coverage & they permit others to use their infrastructure. Permit Tax Breaks for 80% of the works to be completed in 3 years and permit another 3 years tax breaks just for the last 20%. We will then have 2 competing national operators for TV & Broadband & non of this blaming the other lot. May see some truly innovative solutions like high speed internet via the incoming mains (with a free smart meter), or street light wimax.

UK Gov don't want OpenReach in foreign hands.

Re: WHO is paying for fiber investment?

@ Steve Davies 3

The Virgin network is a FTTC type system, the connection from your home to their street furniture is coax, not fibre, i suspect from their street cab to the up stream distribution point is fibre.

I wish OFCOM would ensure VM make that clear on their adds instead of letting them say their service is Fibre Optic, when its not to/from the home.

Re: Why do government projects fail?

@ Kubla Cant

the companies that bid for projects know the real money is made in the indecision of the customer and changing requirements. I've been on both sides of the coin and whilst its not an open discussion to deliberately confuse and cause indecision the opportunity is plainly there for those savy enough to play the game which they see rewarded in their pay, bonus and progression. Its often asked why the useless ones get promoted, its because they extract most cash from the customers.

The PM's are usually useless with no idea what they are doing and are influenced by those that speak their language and not those with the skills to actually build and or rectify the issues. Running a successful project in their eyes is not always the same as what you, I , the public or their customer would expect.

Re: Consequence

@AC a human may read and sympathise but the program assessing your history wont and the policy of whoever cares to check your history will likely not be flexible enough to authorise whoever it is your talking to to take that into account. It will require a lot of unnecessary effort on your part to rectify a blemish on your credit report. Also if you get 3 strikes before its a problem, you now only get 2 through no fault of your own.

Taiwan incumbent adds G.fast to tech mix

chris 17
Bronze badge

so we know its difficult to install anything new in almost any built up location in the first world. The answer must be to make better use of existing infrastructure, G.Fast, or develop some kind of new infrastructure that does not rely on having to install new cables to every building.

Most buildings have a phone line, mains electric & mains water, access to radio waves, some have mains gas.

so either use the electric cables as they conduct, or use radio waves.

Why is that idiot Osbo continuing with austerity when we know it doesn't work?

chris 17
Bronze badge

Increased Government spend these days seems to go to either foreign owned companies or those that rely on off shoring jobs to provide the services for government. When increasing Government spending, the extra money should be staying in these shores not propping up another countries economy at our tax payers expense. Then and only then will the leftist view of increased government spending have some chance of abating a downturn.

WTF?

Re: What the...?

@nematoad "60.4% did not vote for all this austerity"

is it really so hard to understand that 60.4% of people voted for different parties with differing views & policies who did not want to join and form a coalition?

39.6% of voters did, however, vote for 1 party and their policies and views. Like it or not, that 39.6% of votes was enough to secure a majority Government in our electoral system. The country has spoken!!

The day when RAM & NV storage become indistinguishable is almost upon us :).

I've been saying for a while its not far off, especially with the fast 2GB/s drives we see now (MacBook) being an indication of what is to come.

We only use RAM because NV storage is too slow for the CPU to do meaningful work, even RAM can be too slow so we have on cpu caches. Having a 1TB disk that's also RAM would be epic.

BT+EE+TV = Quad play = dangerous to sky

Sky + O2 = quad play but only to try and cover BT

Oddly Virgin Media don't really feature in this battle between Sky ad BT.

VF risk being marginalised if they don't do something here. They either make a play to partner with sky (their former CW net could be attractive for cheap BB backhaul), or they join the Quad play battle by buying VM.

VF + VM quad play would be the only real challenger to BT's ambitions, but VF + sky would blow BT out of the TV & Mobile markets completely

if they really want to do this then they should rap it in law that says for confidential internal NHS use only, no sharing, any change in the law permitting sharing will result in destruction of the data.

Then they can gather data and get the research they want. If they want to extend teh project they will have a template to work from and experience in handling this data

Its a bit like the guy with the 17" MBP who spends all day connected via thunderbolt to a large screen complaining about how hard it is to replace the pcie disc expecting to replace it every few years. just buy a big disk at the start and have a bigger disc connecetd by thunderbolt for backups etc. The pcie disc is much much faster than the sata ssd's available now. if you need to send the machine off, just erase the disc and restore from backup on its return, & how often do you expect it to go for repair?

Smart grid security WORSE than we thought

chris 17
Bronze badge

they likely designed the system at a time when compute to encrypt was expensive and defined a custom low cpu encryption system to save on cost. Now compute is vastly cheaper, what started as a good idea is now exposed as a false economy. Instead of strengthening the custom encryption they should just admit defeat and use industry standard encryption, infact, just install a lightweight bsd or redhat build with facility for ota updates, then when the industry standard is proven broken, they can apply the open source fixes accordingly (they would get proper support with redhat too- and someone to blame). the meter should have a normal display as backup too so we can continue to manually update teh utility with the reading.

Does that make sense to anyone? Are they suggesting it'll mess with your device even if WiFi is off as in airplane mode but you are still in range?

if so that surely makes a mockery of airplane mode where your device is still talking via radio?
