Transfers of IPv4 Addresses from /8s Held by One Organization

Guest post on IPv4 Address market by Sandra Brown Some interesting insights into the IPv4 address market by Sandra Brown who has been working this space for a number of years now. Read on. In 2011, as Nortel’s Director of Engineering I started the orchestration of the sale of Nortel’s 47.0.0.0/8.  Over time this undertaking […]

NANOG 66 is in San Diego by the sea @LONAP

NANOG 66 – bring your shorts One of the downsides perhaps of being in the internet plumbing industry is that your Facebook timeline constantly fills up with people  off to conferences in exotic places. Even when they aren’t off to a meeting people are still off to exotic places as they spend their air miles. This week […]

No matter who you vote for…

James Blessing discusses technology regulatory issues he sees that should be addressed by the next government. Since we have a potential change of government coming up, it might be useful to see how well the current one has been doing in the telecoms and technology space and where the next one might repeat the same […]

Business case for IPv6 #UKNOF29

Participants at UKNOF29 in Belfast were unconvinced that there was a business case for IPv6 It’s over three years since the UK networking industry got together to celebrate the end of the internet as we knew it. The trefor.net “Move over IPv4, Bring on IPv6” party in the London Transport Museum in Covent Garden had […]

Live blogging from #UKNOF29 and Internet Society ION Conference in belfast next week

Look out for live blogging from UKNOF29 and the Internet Society ION conference in Belfast next week. UKNOF, or the UK Network Operators Forum have really interesting conferences three times a year. I’ve often thought one could fill the blog for  week or two with posts based on the content. The problem is that it […]

Kitchen of things – the connected juicer #IPv6 #internetofthings

The connected kitchen, made possible by IPv6 and the internet of things is something oft discussed. Fridges that remind you when you need more milk or when the milk is about to go off is one “useful” and habitually touted suggestion that springs to mind. I was recently chatting to my mam and dad about […]

Nest Labs – tax benefits and the internet of things? #IPv6

Google has bought Nest Labs for $3.2Bn. Nest Labs is into smart home devices and the internet of things. This we all know because it’s splattered all over the tech pages this morning. I’d never heard of Nest Labs. I suspect it’s a by product of living in sleepy old Lincoln, somewhere in the deepest […]

IPv6 usage in UK lagging behind our major global competitors

This graph of  percentage IPv6 adoption by country as of today, 14th October 2013, was extracted from potaroo.net. It shows the percentage of internet users in each country using IPv6. You can get the exact numbers from potaroo. The UK’s 34th place suggests we are seriously lagging behind. OK we can look at it in […]

IPv6 traffic hits 2% of traffic at Google

IPv6 came up in conversation over lunch this week. Google reports that up to 2% of traffic to its servers are IPv6. It took about 4 1/2 years for IPv6 to hit 1% which it did around February of this year and I guess another 7 months or so to then double (timeframes are imprecise […]

Disturbing news re internet traffic growth forecast – prefix exhaustion

I’m doing some prep for a talk next week and just discovered a disturbing fact. I’m sure all of you will have read Cisco’s annual network traffic forecast. I covered it here. What you need to know about is that Cisco reckons that by 2017, global IP traffic will reach an annual run rate of […]

A few observations on the Cisco Annual VNI Report 2012 – 2017

I live in my own little world. It’s a connected world but relatively contained. I have a modest 2,461 followers on Twitter, 455 friends on Facebook and over 5001 connections of LinkedIn. All this comes in to perspective when you read Cisco’s annual Visual Networking Index, a body of research that charts the growth of […]

#WorldIPv6day marked with industry summit in UK

Just come out of committee room 19 at the House of Commons where a “summit” was held to discuss the state of IPv6 readiness of UK plc. The summit was chaired by Ed Vaizey, Internet minister and together with Timico had representatives of the other top network operators aka BT and Virgin. The mix was […]

APNIC starts to ration IPv4 addresses #ipv6

The Asia Pacific Regional Registry APNIC has, as of today, begun to ration IPv4 addresses. Down to its last /8 block (around 16 million addresses) APNIC will now only be issuing  existing users with /22 blocks of 1,024 addresses and is urging its customers to accelerate their adoption of IPv6. European registry, RIPE, is expected […]

testing your endpoint for ipv6 readiness

IPv6 is very much in vogue at the moment.  test-ipv6.com is a useful site you can visit that tells you how prepared you/your connection/your ISP are for IPv6. I’ve run some tests on two connections for you to compare the results. One is IPv4 only and the other dual stack IPv4/IPv6. The difference is self […]

The day we nearly lost the internet #ipv6

Euphoric from the success of bringonipv6.com we hit the town in London last night. Adrian Kennard of AAISP had brought along his “internet in a box” as a laugh. For those of you not in the know the TV programme “IT Crowd” have a box with a flashing LED light on top of it that […]

bringonipv6 event London Transport Museum #ipv6

We have moved over IPv4 and brought on IPv6. Last night’s event at the London Transport Museum turned out to be a raging success. 300 or so people queued around the Piazza at Covent Garden to get in. Many more were watching the IPv6 twitter hashtag which had 1,235,715 impressions with exposure to 250,000 people. […]

Move over IPv4 Bring on IPv6 event sold out but more sponsorship secured – expect more tickets to be available

The first tranche of tickets has all but sold out for this event. If when you register there are no more spaces don’t worry – just get your name on the waiting list. I’ve been able to secure additional sponsorship and expect to be able to increase the number of partygoers. The demand for tickets […]

Moveover IPv4 Bring on #IPv6 Party

We are marking the end of the internet as we know it with a celebratory event on the evening of 22nd March at the Highly Prestigious London Transport Museum in Covent Garden. This gig isn’t just to bury IPv4 though. It is also a serious look at where the world is at with the roll […]

Significant IPv4 announcement to be made in Miami tomorrow #IPv6

Those of you who have been following the countdown to exhaustion of the IPv4 address space will want to tune in to a webcast coming out of Miami tomorrow at 9.30 EST (GMT+5hrs). It is an open secret that this will be the IANA handover of the last 5   /8 blocks of IPv4 addresses. We in the UK will be […]

Last 2 IPv4 blocks allocated – STOP PRESS

The last two available /8 blocks of IPv4 addresses have been allocated by IANA to APNIC.  This takes the remaining total down to 5 which means the IPv4 address pool is effectively exhausted. The last 5 are spoken for. There are no more. That’s it :). I’m holding off crying “history, history” until the remaining […]

IPv4 exhaustion likely to happen this week

Word on the street is that APNIC will ask IANA for two /8 blocks of IPv4 addresses this week.  The IPv4 exhaustion counter (embedded here) suggests that there are 8 days to go – we are pretty much at the end. This will effectively bring the IPv4 saga to a close – once these two blocks […]

The end of #IPv4 and the coming of #IPv6 – exclusive interview with The Young Journalist Academy

Over the past few days I have had a flurry of media interviews on the subject of the exhaustion of the IANA IPv4 address pool and the advent of IPv6. This is increasingly going to be a talking point during 2011. The biggest problem in linking to these interviews is that they are usually on […]
