The best engineers on the planet are coming to the same conclusion: a hybrid 4G/WiFi/landline network is the way to meet mobile demand. Folks like John Donovan of AT&T and Masayoshi Son of Softbank in Japan had this vision around 2007-2008. As the iPhone/iPad/Android made the coming demand clear, networks planners around the world evolved similar strategies. more
It's January again, and being the start of another year, it's as good a time as any to look at the last 12 months and see what the Internet was up to in 2010. This is an update to the report prepared 12 months ago when looking at 2009, so lets see what has changed in the past 12 months in addressing the Internet, and look at how address allocation information can inform us of the changing nature of the network itself. more
Our recent cooperation with the OECD on IPv6 deployment inspired us to provide more IPv6 deployment statistics to a wider audience - from network operators to national governments. The result is an infographic that shows the percentage of networks or Autonomous Systems that announce one or more IPv6 prefixes in the global routing table. This metric shows how many networks have actually deployed IPv6 in a country or group of countries. more
All effective spam filters use DNS blacklists or blocklists, known as DNSBLs. They provide an efficient way to publish sets of IP addresses from which the publisher recommends that mail systems not accept mail. A well run DNSBL can be very effective; the Spamhaus lists typically catch upwards of 80% of incoming spam with a very low error rate. DNSBLs take advantage of the existing DNS infrastructure to do fast, efficient lookups. A DNS lookup typically goes through three computers... more
I attended the RIPE 61 meeting this month, and, not unexpectedly for a group that has some interest in IP addresses, the topic of IPv4 address exhaustion, and the related topic of the transition of the network to IPv6 has captured a lot of attention throughout the meeting. One session I found particularly interesting was one on the transition to IPv6, where folk related their experiences and perspectives on the forthcoming transition to IPv6. I found the session interesting, as it exposed some commonly held beliefs about the transition to IPv6, so I'd like to share them here, and discuss a little about why I find them somewhat fanciful. more
This year's Cisco Collaboration Summit was a step up from last year, and I say that for good reason. Last year's event was good -- all of Cisco's events are good -- but the venue was too small and it took away from the messaging. For 2010, Cisco went out of town to the classy and classic Arizona Biltmore in Phoenix. They don't build them like this anymore, and to me, this setting did far more justice for what Cisco has to say about collaboration. more
There are many big questions in telecom these days, and this is one that's on my mind right now. Over the past few months, I've participated in events or briefed with leading vendors in our space, namely Avaya, ShoreTel, BroadSoft, Aastra, Metaswitch, Mitel, Interactive Intelligence, and this week Cisco. Every analyst has their own core circle of vendors they stay close to, but I'd say that's a pretty fair representation of who's driving telecom. To varying degrees, all of these vendors have a cloud story, and the more I hear it, the more I start to wonder what it really means. more
In August 2010, we looked at the growth in RIPE NCC membership and concluded that the number of new RIPE NCC members is still growing at an amazing pace, even during the recent economic downturn... This time we are looking at the different sizes of RIPE NCC members over time. It is often claimed that there is massive consolidation happening in the ISP community, especially in times of economic difficulties like in the early 2000s and now. We were curious to find out if this is really the case. more
China missed out on playing a leadership role in the development of 3G and as we predicted at that time, China would most certainly start looking at 4G for a major involvement in developing the technologies for it. more
If you haven't noticed lately, spam levels around the world have started dropping especially in October after a couple of events occurred. The first is a Russian crackdown on alleged spam king Igor Gusev, thought to be involved in the operations of SpamIt.com. SpamIt mysteriously shut down in late September, perhaps because Gusev caught wind of law enforcement starting to take notice of him. more
