IPv6: The High VoLTEage Telephony Generator

According to IDC, smartphones outsold personal computers, laptops included in Q4 2010! Nokia just announced the demise of the Venerable Symbian in favour of Windows 7 phone and Microsoft's bing search engine! Tectonic shifts are under way to adapt to the rise of wireless broadband, an all IP world, and the growing weight of Apple and Google Android. It is also time to head once again for Barcelona with the Mobile World Congress starting on the 14th. Highlights this year?

How a Routing Prefix Travels Through the Internet

What happens when an IP address prefix gets announced or withdrawn. How does this information propagate through the Internet? And how does it affect the amount of Border Gateway Protocol (BGP) traffic across the Internet when a single prefix is freshly announced or withdrawn from the global routing table? The following short analysis shows the detailed effects of these two events.

Recent Enhancements to ARIN’s whoIS-RWS Service

ARIN deployed a series of enhancements to its Whois-RWS service today. This includes enabling CIDR support and IPv6 lookups in the search box on the web page, provided plain text rendering of lists of ASNs and networks on the web - plus enhanced CIDR query matching on WHOIS port 43.

Avaya’s web.alive - Another Approach for Unified Communications?

Earlier this month, Avaya held a new type of customer event in Toronto, called Evolutions. They have been looking for better ways to bring customers together, so aside from their global event, they've put together Evolutions, which has a regional focus. The first one was recently held in Mexico to great success, and my understanding is that Canada was the next trial event, and that's what I attended in downtown Toronto... I'm almost certain I was the only Canadian analyst invited, so this may well be the only place you'll hear about Evolutions.

Policy Failure Enables Mass Malware: Part I (Rx-Partners/VIPMEDS)

This is the first in a series of releases that tie extensive code injection campaigns directly to policy failures within the Internet architecture. In this report we detail a PHP injection found on dozens of university and non-profit websites which redirected visitor's browsers to illicit pharmacies controlled by the VIPMEDS/Rx-Partners affiliate network. This is not a unique problem, however the pharmacy shop sites in question: HEALTHCUBE[DOT]US and GETPILLS[DOT]US should not even exist under the .US Nexus Policy.

House of Cards

Time flies. Although it was over 18 months ago, it seems just like yesterday that a small Czech provider, SuproNet, caused global Internet mayhem by making a perfectly valid (but extremely long) routing announcement. Since Internet routing is trust-based, within seconds every router in the world saw this announcement and tried to pass it on. Unfortunately, due to the size of this single message, quite a few routers choked -- resulting in widespread Internet instability. Today, over a year later, we were treated to a somewhat different version of the exact same story.

Psst - Interested in Some Lightly-Used IP Addresses?

The Internet Service Provider (ISP) community is carefully watching the impending depletion of the unassigned IPv4 address pool. Most estimates place the depletion of the central pool of unassigned IPv4 addresses by mid-2011. After that, each Regional Internet Registry (RIR) will continue to satisfy requests for additional IPv4 space for a limited time (depending on the rate of incoming requests and the amount of address space on hand in the RIR at the time of central pool depletion).

Cisco’s Kevin Shatzkamer Discusses the Future of Mobile Video

Kevin Shatzkamer, Chief Architect for Cisco Mobility, speaks to the mobile research Cisco has developed in helping Mobile Service Providers reach their ROI goals and objectives in projecting an increasingly demand driven market. ... There has been speculation for years that increased demand for mobile video would tax and possibly crash current networks and infrastructures of mobile operators. A predictor may be The World Cup games held in South Africa.

At the ARIN Meeting

I have been attending the American Registry for Internet Numbers (ARIN) meeting in Toronto. ARIN is one of the RIRs, i.e., the Internet address registry and policy making authority for North America. Although I have observed and participated on RIR lists for some time and interacted with RIR representatives at ICANN, WSIS and IGF, this is the first time I have been able to attend a meeting. I'm glad I did.

Current ICANN Policy Precludes the ITU Becoming an IP Address Registry

Lost in all the discussion around the recent ITU meeting (TIES account required of course) is any discussion of the current policy regarding the formation of new RIRs. You may recall that one of the reports that the ITU commissioned on this subject suggests that it would be possible, even desirable for the ITU to be allocated a /12 of IPv6 from the IANA to be further allocated to Country Internet Registries.
