DHCP for IPv4 vs. IPv6 - What You Need to Know

Dynamic Host Configuration Protocol (DHCP) is a protocol intended to enable machines (servers, game consols, etc) wishing to be "online" the ability to request Internet Protocol information from a DHCP server automatically. ... In this article we will begin to outline some of the fundamental differences between DHCPv4 and DHCPv6, explore historical uses of DHCPv4 and how those concepts will adapt/change in IPv6. more»

Explaining China's IPv9

Recently, the news that China is adopting IPv9 is making rounds on the Internet. While some of them write off as an April Fool's joke (in July?) like RFC 1606, other wonders if there are more than meets its eyes. But most of them wonders what is this IPv9 and how does it actually works. And some of the English translated article are so badly done that it is impossible to get any useful technical information except that 'It is developed and supported by Chinese government!' more»

Is the Internet Dying?

There are indications that the Internet, at least the Internet as we know it today, is dying. I am always amazed, and appalled, when I fire up a packet monitor and watch the continuous flow of useless junk that arrives at my demarcation routers' interfaces. That background traffic has increased to the point where it makes noticeable lines on my MRTG graphs. And I have little reason for optimism that this increase will cease. Quite the contrary, I find more reason to be pessimistic and believe that this background noise will become a Niagara-like roar that drowns the usability of the Internet. And the net has very long memory... more»

Adult-Related TLDs Considered Dangerous

In an RFC prepared by Donald E. Eastlake 3rd and Declan McCullagh, an analysis is offered for proposals to mandate the use of a special top level name or an IP address bit to flag "adult" or "unsafe" material or the like. This document explains why these ideas are ill considered from legal, philosophical, and technical points of view: "Besides technical impossibility, such a mandate would be an illegal forcing of speech in some jurisdictions, as well as cause severe linguistic problems for domain or other character string names." more»

IPv6: Extinction, Evolution or Revolution?

For some years now the general uptake of IPv6 has appeared to be "just around the corner". Yet the Internet industry has so far failed to pick up and run with this message, and it continues to be strongly reluctant to make any substantial widespread commitment to deploy IPv6. Some carriers are now making some initial moves in terms of migrating their internet infrastructure over to a dual protocol network, but for many others it's a case of still watching and waiting for what they think is the optimum time to make a move. So when should we be deploying IPv6 services? At what point will the business case for IPv6 have a positive bottom line? It's a tough question to answer, and while advice of "sometime, probably sooner than later" is certainly not wrong, it's also entirely unhelpful as well! more»

NAT: Just Say No

Fueled by the lack of public IP addresses, 70% of Fortune 1000 companies have been forced to deploy NATs (Source: Center for Next Generation Internet). NATs are also found in hundreds of thousands of small business and home networks where several hosts must share a single IP address. It has been so successful in slowing the depletion of IPv4 addresses that many have questioned the need for IPv6 in the near future. However, such conclusions ignore the fact that a strategy based on avoiding a crisis can never provide the long-term benefits that solving the underlying problems that precipitated the crisis offers. more»

Why NAT Isn't As Bad As You Thought

Please do sit down. Should the shock cause you to suddenly lose consciousness, I hereby disclaim all responsibility for any subsequent loss or injury. I'm about to defend the anthrax of the Internet: NAT. Network Address Translation is a hack to enable private IP addresses on one side of a router (inside your network) to talk to public IP addresses on the other side (on the Internet, outside your network). It really doesn't matter how it works. The consequence is that unless the router is specifically configured, outsiders can't get in uninvited. So those on the inside can't, by default, act as servers of any service to the outside world. more»

Cricket Liu Interviewed: DNS and BIND, 5th Edition

In follow-up to recent announcement on the release of the latest edition of the very popular DNS and BIND book -- often referred to as the bible of DNS -- CircleID has caught up with Cricket Liu, co-author and a world renowned authority on the Domain Name System. In this interview, Cricket Liu talks about emerging issues around DNS such as security and IPv6 support, and important new features such as internationalized domain names, ENUM (electronic numbering), and SPF (the Sender Policy Framework). "Cricket Liu: We're now seeing more frequent attacks against DNS infrastructure. ...Turns out that name servers are terrific amplifiers -- you can get an amplification factor of nearly 100x. These attacks have raised awareness of the vulnerability of Internet name servers, which is possibly the only positive result..." more»

Verizon Mandates IPv6 Support for Next-Gen Cell Phones

Cell phone carriers have seen a huge growth in wireless data usage. The iPhone is selling like hotcakes, and its users generate large amounts of traffic. Not surprisingly, as cellular providers deploy faster network technologies, users generate even more data... more»

Bad Journalism, IPv6, and the BBC

Here's a good way to frighten yourself: Learn about something, and then read what the press writes about it. It's astonishing how often flatly untrue things get reported as facts. I first observed this back in 1997 when I was a Democratic lawyer in the U.S. House of Representatives working on the (rather ridiculous) campaign finance investigation. (The investigating committee's conspiracy-minded chairman was famous for shotgunning pumpkins in his backyard in order to figure out exactly how Hillary snuffed Vince Foster)...More recently, I've seen the same discouraging phenomenon in reporting on technology and, in particular, the Internet. more»

Anyone Who Still Thinks IPv6 Won't Happen Clearly Isn't Watching the Measurements

Anyone who still is using the "I'll-just-wait-on-IPv6-because-it-will-never-happen" approach is clearly NOT watching the measurements. First, there was the news last week that Google's IPv6 measurement had crossed over 3% less than five months after crossing the 2% mark. Then today comes word from the World IPv6 Launch measurements program that the February 2014 measurements are up... more»

IP Address Exhaustion In 12 Easy Questions

It seems that there is an increasing level of interest in the topic of IPv4 address exhaustion, so I thought I'll share a set of answers to the most common questions I've been asked on this topic in recent times. ... If there is a common factor in many of these challenges, it is scaling the network to meet an ever expanding agenda of more users, more devices, more traffic, more services and more policies. more»

Twenty Myths and Truths About IPv6 and the US IPv6 Transition

After hearing over 350 presentations on IPv6 from IPv6-related events in the US (seven of them), China, Spain, Japan, and Australia, and having had over 3,000 discussions about IPv6 with over a thousand well-informed people in the IPv6 community, I have come to the conclusion that all parties, particularly the press, have done a terrible job of informing people about the bigger picture of IPv6, over the last decade, and that we need to achieve a new consensus that doesn't include so much common wisdom that is simply mythical. There are many others in a position to do this exercise better than I can, and I invite them to make a better list than mine, which follows. more»

Comments on an IP Address Trading Market

With IPv4 addresses becoming scarcer, there has been talk that a trading market will develop. The idea is that those holding addresses they do not really need will sell them for a profit. More alarming is that there have been a few articles about how the Regional Internet Registries (RIR) are contemplating creating such a market so that they can regulate it, conceding that it will happen anyway and taking the "if you can't be 'em, join 'em" attitude. This is all a bit disturbing. Maybe I'm na├»ve, but it's a little unclear to me how an unsanctioned trading market could really operate without the RIRs at least being aware... more»
