Why Integrating IPAM Matters and How to Achieve It

IPAM solutions are the source of truth for IP resources on the network, but when performing IPAM functions such as assignments, reconciliations, DNS updates, network plans, or Regional Internet Registry (RIR) requests, IPAM is often limited by its integration with an OSS. Operational teams can find it challenging to complete routine tasks without an integrated IPAM solution due to siloed data pools and swivel-chair environments. more

Names, Numbers and Beyond…

Couple of weeks ago I started a new initiative called "Names, Numbers and Beyond". I started this as I genuinely think we are facing big issues due to the uncontrolled and non-standard growth of the IP and Name space used today and tomorrow. To keep in control and make everything manageable, parcelling out IP address space and the use of tight naming standards/policies is necessary to make networks work better and make them achievable. more

Aligning Broadband and Healthcare

For many years I have been saying that in order to generate business cases that will support the developments of national broadband networks it is necessary to take into account the social and economic benefits of such investments. The reality is that these benefits do not show up on the balance sheets of the traditional telecoms infrastructure companies and this is a key reason they are reluctant to make such investments. more

The Internet’s Address Crisis: IPv4 Stalls, IPv6 Stagnates

Despite the long-anticipated exhaustion of IPv4 addresses, the Internet continues to function through clever workarounds, market transfers, and cautious optimism, while IPv6 adoption remains slow and the future of global connectivity appears uncertain. more

The Next Development in Wireless Broadband

In the USA the FCC has started the discussion on the next level of telecoms in the wireless market, aimed at making spectrum in bands above 24GHz available for flexible-use of wireless services, including next-generation, or 5G networks and technologies. New technologies such as massive-MIMO are going to make it possible to deliver 'fibre-like' speeds over short distance wireless networks operating in the 24+GHz bands. This will make the technology especially useful for high-speed broadband services in densely populated areas. more

In Response to ‘Networking Vendors Are Only Good for the Free Lunch’

I ran into an article over at the Register this week which painted the entire networking industry, from vendors to standards bodies, with a rather broad brush. While there are true bits and pieces in the piece, some balance seems to be in order. The article recaps a presentation by Peyton Koran at Electronic Arts (I suspect the Register spiced things up a little for effect); the line of argument seems to run something like this... more

Gambia Criticized for Shutting Down Communication Networks on Election Day

"Communication blackout shatters illusion of freedom during the election," says Amnesty International in a statement on Thursday. more

The Christmas Goat and IPv6 (Year 13)

2022 was not a normal year for me. We sold our company of almost 25 years to Interlan Gefle AB to Nordlo Group, and I also moved away from Gävle city to Boänge, a small rural village outside Sandviken where my ISP (AS20626) still isn't ready for IPv6 in my location.... ☹ ( I use a Mikrotik with a Wireguard tunnel to solve my IPv6 today.) It's 2023 when I'm writing this, and I can't understand why ISPs still haven't deployed IPv6! more

Nerd Knobs and Open Source in Network Software

Tech is commoditizing. I've talked about this before; I think networking is commoditizing at the device level, and the days of appliance-based networking are behind us. But are networks themselves a commodity? Not any more than any other system. We are running out of useful features, so vendors are losing feature differentiation. This one is going to take a little longer... more

Using LEOs and GEOs

Once you head away from the areas serviced by modern terrestrial cable infrastructure, the available digital communications options are somewhat limited. Some remote areas are served using High-Frequency radio systems, using radio signals that bounce off the ionosphere to provide a long-distance but limited bandwidth service. Or there are satellite-based services based on spacecraft positioned in geostationary orbital slots. more

Fierce Political Battle Expected as FCC Chair Elaborated on Plan to Reverse ‘Net Neutrality’ Rules

FCC Chairman Ajit Pai speaking in Washington today, said he wants to reverse rules that boosted government regulatory powers over Internet service providers. more

So You’ve Got Some Big Data, but Now What?

As Internet connection continues on a steady path of becoming a ubiquitous commodity in mature markets, we saw an eruption of big data tracking and analysis software in 2014. But what are operators going to do with all this new information? And how can they turn data into revenue? To start with, providers need more than just a data measurement tool. They need a solution that can analyze real-time data and then automate processes to optimize their networks and improve their subscribers' experiences. more

Rethinking Protection Technologies: A Change Has Occurred

Talking technical is easy. Distilling technical detail, complex threats and operation nuances down to something that can be consumed by people whose responsibility for dealing with cybercrime lays three levels below them in their organizational hierarchy is somewhat more difficult. Since so many readers here have strong technical backgrounds and often face the task of educating upwards within their own organizations, I figured I'd share 4 slides from my recent presentation that may be helpful in communicating how the world has changed. more

Blocking and Filtering in Collaborative Security Context - A Reflection on RFC 7754

The other day, I planned to take my 15-year-old son to the movie theatre to see "Hateful Eight" in 70mm film format. The theatre would not allow him in. Under article 240a of the Dutch penal code, it is a felony to show a movie to a minor when that movie is rated 16 or above. Even though I think I am responsible for what my son gets to see, I understand that the rating agency put a 16-year stamp on this politically-incorrect-gun-slinging-gore-and-curse-intense-comedy feature. more

China and Taiwan to Lead the Development of 4G

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
