What happens when an IP address prefix gets announced or withdrawn.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the amount of Border Gateway Protocol (BGP) traffic across the Internet when a single prefix is freshly announced or withdrawn from the global routing table?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. more
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. more
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. more
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. more
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. more
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). more
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. more
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. more
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. more
In January we presented the glorious history of the MIT spam conference, today we present the schedule for the first day. Opening session will be from this author, Garth Buren with a topic entitled The Internet Doomsday Book, with details be released the same day as the presentation. Followed by Dr. Robert Bruen with a review of activities since the last MIT spam conference... more
