One idea to make the problem of mail more manageable is to restrict the address space that is allowed to send mail. In an ideal world, we'd restrict where mail mail servers could send mail from. So, if we say that the number of individual mail servers in the world will probably never exceed 32 million (not unreasonable), or 2^25, then what if the 25 least significant bits were reserved for mail servers? more
Who would dare to predict the year the Internet will reach 50 billion addressable devices? Thomas Noren, head of LTE product development at Ericsson sees one day 50 billion devices shouldered by LTE. He sees LTE as the truly global standard putting to rest the long and acrimonious rivalry between CDMA and GSM protagonists and even sees the Chinese third way with their TD-SCDMA aligned on LTE. Mobile WiMax is, in his mind, already relegated to the dustbin of history... more
We know that the Internet is running out of IPv4 addresses and that some in our community check twice a day Mat Ford's doomsday clock or spend an hour once a week reading the tea leaves based on Geoff Huston's exhaustive data compiled at Potaroo. Like with global warming, there is still a school of thought out there arguing that this running out of IP addresses is just fear mongering and that we are not really running out of IPv4 addresses as a NATted world is more than adequate to run the Internet for the foreseeable future. We know that the Internet is running out of AS... more
About a year ago, we shared some graphs that showed the percentage of IPv6 enabled networks over time. More precisely, it showed the percentage of Autonomous Systems (ASes) that announced one or more IPv6 prefixes in the global routing table. The results for the five Regional Internet Registries (RIRs) were described in an earlier CircleID post... We looked at the progress since then. more
"The world is flattening," says Dave Rubal at the FOSE Conference and Exhibition this week in Washington, DC. "The race for IT dominance is on, and it is coming west." Mr. Rubal, Cisco's Worldwide Internet Protocol version 6 (IPv6) Task Force Lead, spoke of the tremendous race in IT dominance that is occurring, stating that the "mainstay technologies at the Beijing Olympics will be IPv6-powered." IPv6 is in line to replace version 4, but Rubal hinted that China and other Far East countries may be adopting the new version faster than the United States... more
We don't give enough credit to people who will sacrifice themselves trying to plug the IPv4 dam with some NAT-putty. They even dream of a NAT66 filled afterlife. The growing IPv6 traffic trickle was given evidence at the recent RIPE 57 meeting in Dubai in a number of presentations, including a most edifying Google presentation. Noteworthy to see France with a 0.65% IPv6 penetration... more
Wide-Area Data Services (WDS), aka "WAN Optimization" is becoming the most effective way to improve application performance while reducing network traffic. In scenarios where there is significant network latency that would otherwise render many applications unusable, WDS can deliver almost LAN-like speed. Where bandwidth constraints exist and there is no practical or economical option, WDS can help reduce network traffic, allowing you to postpone or avoid circuit upgrades altogether. The technology provides the ability to centralize applications and servers, furthering the cost savings on hardware, software licensing, maintenance and the operation of a distributed architecture. more
It is an open secret that the current state of IPv4 allocation contains many accidental historical imbalances and in particular developing countries who wish to use IPv4 are disadvantaged by the lack of addresses available through ordinary allocation and are forced into purchasing addresses on the open market. As most of the addresses for sale are held by organisations based in the developed world, this amounts to a transfer of wealth from the developing world to the developed world, on terms set by the developed world. more
This is the eighth year we measure IPv6 on the Christmas Goat. And with the crazy climate we have to live in now where there is no snow on the goat or ground. But IPv6 is doing better than the climate this year. This year we increased from 27% 2016 to 40% 2017. In Sweden Tele2, Tre and Comhem are still the only major ISPs with IPv6 enabled. Tele2 (with IPv6 since ~three years) and Tre is mostly mobile operators, and Comhem has enabled IPv6 in their Docsis network. more
Time for another annual roundup from the world of IP addresses. What happened in 2012 and what is likely to happen in 2013? This is an update to the reports prepared at the same time in previous years, so lets see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself. more
I opined about a year ago that DNS blacklists wouldn't work for mail that runs over IPv6 rather than IPv4. The reason is that IPv6 has such a huge range of addresses that spammers can easily send every message from a unique IP address, which means that recipient systems will fire off a unique set of DNSBL queries for every message... Now I'm much less sure this will be a problem... more
Exponential growth of networks combined with the complexity introduced by IT initiatives e.g. VoIP, Cloud computing, server virtualization, desktop virtualization, IPv6 and service automation has required network teams to look for tools to automate IP address management (IPAM). Automated IPAM tools allow administrators to allocate subnets, allocate/track/reclaim IP addresses and provide visibility into the networks. Here are some examples of what a typical IPAM tool can do... more
The number of applications this year for the seven positions within ICANN has been so low that the NomCom has gone to the trouble of printing up pamphlets, holding a public meeting at Marrakech and extending the deadline by a fortnight. At the two public Board sessions in Marrakech the grand hall that was provided was virtually empty, sparking some debate as to why. Susan Crawford ventured that it was because ICANN was failing to connect with people; Vint Cerf suggested that ICANN was so successful at doing its job that people didn't feel the need to attend. Mouhamet Diop pointed out that we were in a French-speaking Arabic country and no one was going to sit through four hours of discussion if they didn't understand a word of it... more
The Internet Society Deploy360 Programme issues a call for speakers for a series of upcoming global ION Conferences. ISOC welcomes submissions from IPv6 and DNSSEC experts to speak at any of the following ION conferences. more
At today's "Managing Critical Internet Resources" session of the Internet Governance Forum 2009, the ITU agenda on taking a role in IPv6 distribution once again reared its ugly head. In a heated exchange, Professor Dr Sureswaran Ramadass, the Director of Nav6 an ITU consultant/fanboy squared off with the new ICANN CEO about competition in IPv6 address distribution. more
