How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more

Coalition for Digital Africa Announces IXP Initiative

This latest initiative announced by the Coalition for Digital Africa will focus on strengthening the Internet infrastructure across the continent by enhancing five existing Internet exchange points (IXPs). The initiative is supported by a grant from ICANN and will be implemented by the Internet Society (ISOC) and will involve identifying five IXPs based on their potential to make a high impact on the respective local and sub-regional markets. 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

Building a More Secure Routing System: Verisign’s Path to RPKI

At Verisign, we believe that continuous improvements to the safety and security of the global routing system are critical for the reliability of the internet. As such, we've recently embarked on a path to implement Resource Public Key Infrastructure (RPKI) within our technology ecosystem as a step toward building a more secure routing system. In this blog, we share our ongoing journey toward RPKI adoption and the lessons we've learned as an operator of critical internet infrastructure. more

Cisco Introduces Intent-Based Network That Can Learn, Adapt and Mitigate Threats

Cisco has launched an intent-based networking solution designed to be intuitive and adapt; a new approach claimed to be one of the most significant breakthroughs in enterprise networking. more

Software Has Already Eaten Telecoms (It Just Has Indigestion)

The unconscious and near-universal belief is that packet networks are a telecoms service, and one that constructs an 'additive' resource called 'bandwidth'. This is demonstrably technically false. They deliver distributed computing services, as they calculate how to divide up an underlying telecoms transmission resource. The ubiquitous error is a failure to recognise that the hardware platform has already been devoured by the software industry. more

Major New Funding Opportunities for Internet Researchers and R&E Networks

Nationally Appropriate Mitigation Action (NAMA) is a new policy program that was developed at the Bali United Nations Climate Change Conference. As opposed to the much maligned programs like CDM and other initiatives NAMA refers to a set of policies and actions that developed and developing countries undertake as part of a commitment to reduce greenhouse gas emissions. Also unlike CDM, NAMA recipients are not restricted to developing countries. more

Keep Your Pants On: Governments Want Suspenders for Secure Routing

The difficulty of applying a hierarchically organized PKI to the decentralized world of Internet routing is being fully exposed in a new Internet-draft. The document represents a rational response to an RPKI that closely ties address resources to a handful of Internet governance institutions, nicely illustrates how governments and national security policy are influencing Internet security, and portends substantial costs for network operators and beyond if adopted widely more

Iran Among Countries Affected by a Cyberattack That Left U.S. Flag on Screens

A hacking incident over the weekend attacked networks in a number of countries including data centers in Iran where they left the image of a U.S. flag on screens along with a warning: "Don't mess with our elections." more

50 Years of Ethernet

The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17^th century to explain how light could be transmitted through a vacuum. more

Prime Real Estate in the Cloud

In the physical world of real estate, value is all about location, location, location. In the virtual world of enterprise business, value is all about performance. The catch is that enterprise performance today is often driven by... location, location, location. When it comes to your digital transformation, and the migration of services to the cloud, the location of your data is paramount. To reach a customer looking to complete an on-line purchase or enable a group of employees trying to collaborate on a shared document, data needs... more

Call for Participation - ICANN DNSSEC and Security Workshop for the ICANN 85 Community Forum

ICANN invites proposals for its DNSSEC and Security Workshop at the ICANN85 Community Forum in March 2026, offering a platform for global experts to share insights on DNS, routing security, and emerging threats. more

Obama to Sign Executive Order for Streamlining Approval of Internet Networks

Currently, the process for approving broadband construction projects on federal property varies from agency to agency. Property controlled by the federal government includes roads, about 30 percent of the nation's land and more than 10,000 buildings. The order will require the Departments of Agriculture, Commerce, Defense, Interior, Transportation and Veterans Affairs as well as the Postal Service to develop a single process for approving Internet construction projects. more

Global IT Outage Disrupts Airlines, Businesses, and Hospitals

A massive IT glitch originating from a software update by cybersecurity firm CrowdStrike has caused significant disruptions worldwide, impacting airlines, businesses, medical facilities, and broadcasters. The issue, identified as a faulty update in Microsoft cloud services, led to widespread outages early Friday. more
