Now that we know a bit more about addresses in a networking stack (read the whole series) and why CLNP uses node addresses while TCP/IP uses interface addresses, let’s see how they solve common addressing problems like finding adjacent nodes.
Let’s start with the elephant in the room: how do you know whether you can reach a host you want to communicate with directly? In the following diagram, how does A know whether B is sitting next to it?
This post describes how to install Active Directory Certificate Services (ADCS) onto a domain controller. It’s for labbing purposes which means I’m going to run this all on a single server instead of a more realistic setup with offline root, issuing CA, and possibly intermediate CA. Don’t use this post for anything designed to go into production!
To add the ADCS role. Go to Server Manager, click Add roles and features. Click Next until you get to Server Roles. Select Active Directory Certificate Series:
Click Add Features. Click Next. Click Next. Then a warning is displayed that it’s not possible to change the computer name or domain settings:
Click Next. Select Certification Authority and Certification Authority Web Enrollment:
Selecting Certification Authority Web Enrollment will install IIS and a small web site will be built to provide certificate services.
Click Add Features. Click Next. Click Next. Select Restart the destination server automatically if required:
Click Install. The installation starts:
When the installation has finished, click Close. Click AD CS in Server Manager. Click More… where it says Configuration required for Active Directory Certificate Services:
Click Configure Active Directory Certificate Services on the destination server:
Select an Continue reading

Cloudflare's network spans more than 330 cities in over 120 countries, serving over 60 million HTTP requests per second and 39 million DNS queries per second on average. These numbers will continue to grow, and at an accelerating pace, as will Cloudflare’s infrastructure to support them. While we can continue to scale out by deploying more servers, it is also paramount for us to develop and deploy more performant and more efficient servers.
At the heart of each server is the processor (central processing unit, or CPU). Even though many aspects of a server rack can be redesigned to improve the cost to serve a request, CPU remains the biggest lever, as it is typically the primary compute resource in a server, and the primary enabler of new technologies.
Cloudflare’s 12th Generation server with AMD EPYC 9684-X (codenamed Genoa-X) is 145% more performant and 63% more efficient. These are big numbers, but where do the performance gains come from? Cloudflare’s hardware system engineering team did a sensitivity analysis on three variants of 4th generation AMD EPYC processor to understand the contributing factors.
For the 4th generation AMD EPYC Processors, AMD offers three architectural variants:
mainstream classic Zen 4 cores, codenamed Continue reading

An Easy Route To AI-Enhanced Productivity was written by Timothy Prickett Morgan at The Next Platform.
Cloudflare One, our secure access service edge (SASE) platform, is introducing a new integration with Okta, the identity and access management (IAM) vendor, to share risk indicators in real-time and simplify how organizations can dynamically manage their security posture in response to changes across their environments.
For many organizations, it is becoming increasingly challenging and inefficient to adapt to risks across their growing attack surface. In particular, security teams struggle with multiple siloed tools that fail to share risk data effectively with each other, leading to excessive manual effort to extract signals from the noise. To address this complexity, Cloudflare launched risk posture management capabilities earlier this year to make it easier for organizations to accomplish three key jobs on one platform:
Evaluating risk posed by people by using first-party user entity and behavior analytics (UEBA) models
Exchanging risk telemetry with best-in-class security tools, and
Enforcing risk controls based on those dynamic first- and third-party risk scores.
Today’s announcement builds on these capabilities (particularly job #2) and our partnership with Okta by enabling organizations to share Cloudflare’s real-time user risk scores with Okta, which can then automatically enforce policies based on that user’s risk. In this way, organizations can adapt Continue reading
In the previous post, Setting up Active Directory for ISE Lab, we enabled Active Directory Domain Services. The DNS role was also added automatically as part of this process. In this post, we’ll add DHCP to the server.
Go to Server Manager, click Add roles and features. Click Next until you get to Server Roles. Select DHCP Server. This will display a window asking if required services should be installed:
Click Add Features. Click Next until getting to the Confirmation screen. Select Restart the destination server automatically if required. Since this is a lab, it’s OK to restart.
Select Yes. Then Click Install. The installation starts:
After the installation finishes, click Close.
The DHCP role has been added:
Let’s configure two DHCP scopes, one for employees and one for guests. Open the DHCP app, then expand the server and then IPv4. Right click on IPv4 and select New Scope…
This launches the New Scope Wizard:
Give the scope a name and a description:
Click Next. Then configure starting IP, ending IP, and the subnet mask:
Click Next. I’m not adding any exclusions so clicking Next again. Then configure the lease duration, I’m setting it to 1 day instead of Continue reading
