Walks Like a Telco, Yalks Like a Telco... Must be a Telco

  Well, Vonage is (a.) still very cheap, (b.) provides good service and (c.) supplies service that even non-computer / non-Skype people can use.  Aside from the $25/month flat rate for US calling, which is cheaper than I was getting before…

Comments on an IP Address Trading Market

• Comment posted Feb 17, 2008 7:13 pm PST — by Dan Campbell
  I agree.  It will be tough to create that much value for individual addresses because they will never be individually routable.  And you can't expect those that are willing to pay $10K or $100K for a single address to somehow…

  Understood.  But I'm not sure where it stands now.  I did a study round about 2002 when the table was like 125,000 routes and I found the bulk, something like 60 or 70%, were /24s.  Those aren't aggregates unfortunately, but…

  McTim, Good comments, thanks.  It's been a few years (actually probably more like 5) since I last turned over address / route management to an operations group, so I wasn't up on the automatic /21 AW.  That's great news.  We…

  Renumbering is never fun and is always a hassle.  For many organizations, I doubt the incentive would be enough to convince them to undergo the risk and effort.  Once the addresses get threaded through servers, applications, network management systems, processes,…

  Regarding Jeff's comments, if I read it right you are just saying that the address transfer occurs when two corporations legally merge.  I have no issue with that.  That's legitimate, albeit odd that a business would acquire another simply because…

  A few more things I forgot to mention.  One, in the first allocation process you also have to show proof of being a legal entity, e.g., incorporated or something similar, in the RIR's territory.  You usually have to show an…

Pakistan Hijacks YouTube: A Closer Look

• Comment posted Feb 25, 2008 11:02 pm PST — by Dan Campbell
  I'm actually surprised this doesn't happen more often, if not inadvertently then as a form of attack.  So much of the Internet indeed depends on trust, it's a wonder it doesn't break down more often.  Smaller ISPs don't have the…

Federal Class Action Lawsuit Filed Against Network Solutions and ICANN

• Comment posted Feb 26, 2008 2:20 pm PST — by Dan Campbell
  I'm glad I wasn't the only one who didn't get the used car analogy! I'd like to know how to get on the plaintiff's list because I got burned by this recently and want my $25 back! NSI has a…

The Front Running Class Action Suit

• Comment posted Feb 27, 2008 9:07 pm PST — by Dan Campbell
  Wouldn't the class in the action be other registrars rather than (or at least in conjunction with) the actual people who registered domains?  The other registrars, like the one I usually use who didn't get my recent business because of…

IPv6 Over Satellite: Pie in the Sky?

  I wonder why IABG chose not to have a booth at the Sat conference this week.  They seem to attend many others.

On Comcast and Net Neutrality: Shouting Fire in a Theater

• Comment posted Mar 04, 2008 12:40 pm PST — by Dan Campbell
  I am not sure how I misinformed anyone about AT&T;’s DSL pricing since I make no mention of it anywhere.  (But I do find it amusing that the word “monopoly” is mentioned in the same post where AT&T;is used as…

• Comment posted Feb 28, 2008 8:50 pm PST — by Dan Campbell
  All good points, but metered services do discourage even relatively mild usage patterns.  With gas prices as they are, I'm quicker to put on a sweater than to crank up the heat even just a few degrees.  Water is relatively…

Why Telcos Don't Get Networks

• Comment posted Mar 05, 2008 8:31 pm PST — by Dan Campbell
  I'd be interested in reading that.  You are correct, it should be about content.  It's like the demand for roads in major cities that result from the "content" inside or surrounding the city, e.g., businesses, jobs, malls, sports arenas, condos,…

Managing Internet as a Shared Resource: Reasonable Technical Constraints?

• Comment posted Apr 08, 2008 8:51 pm PDT — by Dan Campbell
  If you have followed the Comcast/FCC story, and if you have read alot of the blogs related to the topic, you'll find that most people (or at least those that feel strongly enough to writea comment) want a complete hands-off…

Sprint's Big Deal: New Life for WiMax

• Comment posted May 07, 2008 2:43 pm PDT — by Dan Campbell
  "Assuming the deal is for real" are the key words.  This has been on again off again more than a Hollywood romance. It seems like every few weeks I pick up the paper and see that this deal is back…

Knowing Less

• Comment posted Jun 12, 2008 1:51 pm PDT — by Dan Campbell
  Content filering is not uncommon on private enterprise / business networks.  The proxy devices, for example Blue Coat, can be configured to be pretty specific, to URL level and user level, or can be configured with general rules that end…

No Fines for Comcast

• Comment posted Jul 15, 2008 2:54 am PDT — by Dan Campbell
  Brett, I'm not sure if I'm reading you right, but I sense that you have a bit of doubt that the P2P problem actually exists.  Trust me, it does.  The behavior of the protocols and the traffic they generate are…

FCC and Comcast: Reasonably Vague

• Comment posted Jul 15, 2008 6:06 pm PDT — by Dan Campbell
  Few people will read the service contract.  Those that do will skim it, probably not understand the part about the shared bandwidth or at least not understand the implication, and even if they do they will likely not remember months…

Deep Packet Inspection: When the Man-In-The-Middle Wants Money

• Comment posted Jul 30, 2008 2:36 pm PDT — by Dan Campbell
  It's hard for me to understand why DPI is generating news now.  It's been around for a long time and is inherent in most networks in many different kinds of devices.  There are many devices that inspect traffic and act…

FCC's Comcast Ruling Inconsistent and Incoherent

• Comment posted Aug 05, 2008 7:13 pm PDT — by Dan Campbell
  No one is necessarily stopping you from running a web server, but if it does suddenly generate tons of traffic, it could have impact, thus the ISPs at least want to discourage it.  As for the assymetry, it affects more…

• Comment posted Aug 05, 2008 12:32 pm PDT — by Dan Campbell
  Joakim, The reasons are simple.  One is technical, that is, the upstream is typically more constrained in bandwidth than the downstream (towards the subscriber) in broadband platforms, and the very assymetric nature of Internet traffic where (typically, at least for…

Hunting Unicorns: Myths and Realities of the Net Neutrality Debate

• Comment posted Aug 11, 2008 2:35 pm PDT — by Dan Campbell
  I use the terms "metered" or "usage-based" liberally to sum up anything that is not flat-rate no-usage-maximum "all you can eat" service, rather than try to come up with terms for th e 50 different permutations of, well, "usage-based" service. …

  The email spam analogy is interesting but ironically can work both ways.  I know what you are saying, but spam has become such a problem that ISPs and business are using invasive tactics to thwart it.  Spam filters often cause…

  Brett, I typically ignore your responses because they tend not to offer much more than sarcasm and criticism, particularly directed towards Richard Bennett to whom you seem to show a particular disdain (and frankly, whose comments are typically on the…

  If the whole Comcast / Net Neutrality argument is purely based on stopping something early before it becomes the slippery slope, then fine.  But you are bringing up things that aren't the case right now.  Comcast uses DPI-based P2P throttling…

  What adult expects the world to be fair?  It's not, never has been, never will be. The Internet is no exception.  The Internet is not (no longer) a Government subsidized service provided for free.  When it was run by the…

Satellite Internet Access That Could Be Good

• Comment posted Sep 10, 2008 6:51 pm PDT — by Dan Campbell
  It will be interesting to find out if their initial deployment will be a dual-stack IPv4/IPv6 network, given the timing of their deployment and the developing (and large) target market they intend to serve.

Comcast's Network Management Practices: A Brief Analysis

• Comment posted Sep 25, 2008 2:33 pm PDT — by Dan Campbell
  Well, there are other protocols besides TCP, and they don’t recover from dropped packets.  VoIP and streaming video are getting more and more popular.  The former is a direct threat to legacy telephony, and the latter, while eventually becoming a…

• Comment posted Sep 23, 2008 6:20 pm PDT — by Dan Campbell
  All it really means is that Comcast is falling back to a more traditional, and apparently more socially acceptable, means of providing QoS on a network (albeit a step above pure Diffserv-based QoS).  Most QoS devices such as Packeteer and…

Comcast is Right, the FCC is Wrong

• Comment posted Sep 30, 2008 8:09 pm PDT — by Dan Campbell
  Mike, So, what are your viewpoints on NAT, PAT, transparent caching, WAN optimization / TCP acceleration, etc.?  These and other technologies are found in abundance on the Internet. They too alter IP addresses, packets, data transactions and protocol interaction.  They…

  There are also several satellite-based Internet access services available, at least Hughes, Starband and Wildblue.  Their satellites cover the whole US of course, a larger area than Comcast or any other cable or DSL provider, although some satellite providers focus…

  Whether you realize it or not, most business are unfortunately best effort no matter how much they disguise it.  (Have you flown lately?) Pretty much everything we do operates on an oversubscription scheme of some sort, whether it is tables…

Net Neutrality an 'American Problem', Australians Suggest Alternatives

• Comment posted Sep 29, 2008 2:54 pm PDT — by Dan Campbell
  First of all, the statement "optical fiber basically doesn't run out of capacity" is not relevant because we are talking about a last (or first!) mile problem.  The Internet backbone is not the issue.  It is technologies like DOCSIS cable…

First Broad Internet Census Since 1982 Reveals Surprising Number of Unused IPv4 Addresses

• Comment posted Oct 16, 2008 2:46 pm PDT — by Dan Campbell
  Yeah, this really isn't the right technique.  Many PINGs will be blocked by firewalls even though the hosts are indeed alive.  And many addresses within live subnets won't actually be assigned to hosts, but they are still "in use" because…

Net Neutrality Advocates: Wireless Carriers' Network Management Must Be 'Reasonable'

• Comment posted Nov 12, 2008 2:04 pm PST — by Dan Campbell
  There really isn't much difference.  All telecom services are built on some sort of oversubscription model, some more extreme than others depending on the underlying technologies and resources available.  Oversubscription is important to ensure that business model can be maintained,…

Free, Slow, Censored Internet: A Bad Idea

  A couple of quick points that have no real effect or add much value ;-)… - I'm not sure dial-up ever "worked fine" unless you mean maybe 1995, and even then....I don't know.  But there are still so many unfortunate…
