Strewth! Aussie ISP gets eye-watering IPv4 bill, shifts to IPv6 addresses

For years, internet engineers have predicted that the cost of an ever-smaller pool of IPv4 addresses would cause people to shift to the internet's new IPv6 protocol. Well, it finally appears to be happening. Speaking at the annual conference of Australian Network Operators late last week, the managing director of ISP Aussie …

Sitting pretty in IPv4 land? Look, you're gonna have to talk to IPv6 at some stage

We can be forgiven for not having weaned ourselves onto IPv6 earlier. It's been around in draft form since late 1998, but was only released as a standard in July 2017 (that'll be RFC 8200). That this has finally happened, though, means we're being told more loudly than ever that we no longer have an excuse. So do we have one? …

Time to dump dual-stack networks and get on the IPv6 train – with LW4o6

Despite a decade of efforts, the rollout of IPv6 is still stubbornly sat at less than 25 per cent, in terms of internet traffic, with recent reports suggesting adoption may actually be leveling off. Among the reasons the world is not shifting en masse to the new addressing system, the most persistent is the fact that people …

OK, this time it's for real: The last available IPv4 address block has gone

You may have heard this one before, but we have now really run out of public IPv4 address blocks. The Internet Assigned Numbers Authority – the global overseers of network addresses – said it had run out of new addresses to dish out to regional internet registries (RIRs) in 2011. One of those RIRs, the Asia-Pacific Network …

Crashed RadioShack flogs off its IPv4 stash

Collapsed retail store RadioShack will auction off its public IPv4 addresses as part of its ongoing bankruptcy proceedings. The 32,000-odd addresses will be sold off in /24 and /20 subnets by auction site IPv4Auctions.com, which specializes in the sale and resale of the increasingly valuable online space. The website says it …

Public IPv4 drought: Verizon Wireless to stop handing out static addys

Verizon Wireless will soon stop issuing public static IPv4 addresses to its business customers “due to a shortage of available addresses.” Instead, it will dish out persistent prefix IPv6 addresses. If you're a Verizon customer and you need a static public address for an IPv4-only device, you'll have to replace that hardware …

One IP address, multiple SSL sites? Beating the great IPv4 squeeze

We're fresh out of IPv4 addresses. Getting hold of a subnet from your average ISP for hosting purposes is increasingly difficult and expensive, even the public cloud providers are getting stingy. While we wait for IPv6 to become usable, there are ways to stretch out the IPv4 space. There are several big problems with IPv6 that …

Global IPv4 address drought: Seriously, we're done now. We're done

You may have heard this before, but we are really, really running out of public IPv4 addresses. This week, the regional internet registry responsible for Latin America and the Caribbean, LACNIC, announced it has moved to "phase 3" of its plan to dispense with the remaining network addresses, meaning that only companies that …

IPv4 is OVER. Really. So quit relying on it in new protocols, sheesh

Well, that took a while. Eighteen years after the IETF brought us IPv6 as an answer to then-looming-now-upon-us IPv4 address exhaustion, the Internet Architecture Board says: no more. Getting IPv6 into the field has been a long, slow slog. According to Google, IPv6 carries just 14.6 per cent of search requests to the web giant …

IPv4 apocalypse means we just can't measure the internet any more

IPv4 address exhaustion is making it harder to measure the size of the Internet, even as IPv6 deployment accelerates. While IPv6 activity doubled in 2015 (to 400 million addresses by year-end), the vast majority of users are still on IPv4 addresses, mostly via dynamic assignment or behind carrier-grade Network Address …

IPv6 now faster than IPv4 when visiting 20% of top websites – and just as fast for the rest

Accessing websites via IPv6 is not only comparable in speed to IPv4, but is actually faster when visiting one in five of the world's most popular sites, according to German researchers. In a new paper, Vaibhav Bajpai and Jürgen Schönwälder from the University of Bremen looked at the response times for the internet's top 10,000 …

Crims set up fake companies to hoard and sell IPv4 addresses

IPv4 addresses are now so valuable that criminals are setting up shell companies so they can apply for addresses, then resell them to users desperate to grow their networks. Criminals are doing so because there are no more IPv4 addresses left: the American Registry for Internet Numbers (ARIN) ran out in September 2015. ARIN …

Are second-hand MoD IPv4 addresses being used in invoice scams?

Crooks appear to be taking advantage of the recent sale of the UK Ministry of Defence’s IPv4 address space to run more convincing scams. They have purportedly bought blocks of IP addresses with previously pristine records to distribute scams. This malfeasance was enabled, in part, because the relevant Whois database entries …

Official: North America COMPLETELY OUT of new IPv4 addresses

North America has officially run dry of new IPv4 addresses, the numbers that computers use to find each other on the internet. This means the region can allocate no more of the 32-bit network addresses to web hosting companies, cloud providers, organizations and individuals: they're all taken. The space is full, and it's being …

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

The American Registry for Internet Numbers (ARIN) can no longer satisfy requests for new IPv4 addresses and has started a waitlist for those who want more. ARIN warned, in early June, that “It is very likely that we are already processing a request that we will be unable to fulfill [sic].” On Monday this week it escalated the …

Ofcom mulls selling UK govt's IPv4 cache amid IPv6 rollout flak

PEAK IPV4? Global IPv6 traffic is growing, DDoS dying, says Akamai

Broadband and IPv6 are hot – and distributed denial-of-service attacks and IPv4 are not. Well, that's according to Akamai. The cache-and-carry-on biz said in its latest State of the Internet report that, for the first time ever, the average connection speed for netizens is more than 4Mbps, meaning your average punter has a " …
