Data Plane Quirks in Virtual Network Devices
Have you noticed an interesting twist in the ICMP Redirects saga: operating systems of some network devices might install redirect entries and use them for control plane traffic – an interesting implementation side effect of the architecture of most modern network devices.
A large majority of network devices run on some variant of Linux or *BSD operating system, the only true exception being ancient operating systems like Cisco IOS1. The network daemons populate various routing protocol tables and compute the best routes that somehow get merged into a single routing table that might still be just a data structure in some user-mode process.

Day Two Cloud 136: The Role And Responsibilities Of A Kubernetes Operator (Sponsored)
Today on the Day Two Cloud podcast we examine the role and responsibilities of Kubernetes operators; that is, the humans in charge of running Kubernetes. Kubernetes operators have to support application and security teams, handle capacity planning, keep an eye on versioning, and more. This episode is sponsored by F5's NGINX team. Our guests are Jenn Gile, Sr Manager of Product Marketing; and Brian Ehlert, Sr Product Manager.iCloud Private Relay: information for Cloudflare customers
iCloud Private Relay is a new Internet privacy service from Apple that allows users with iOS 15, iPadOS 15, or macOS Monterey on their devices and an iCloud+ subscription, to connect to the Internet and browse with Safari in a more secure and private way. Cloudflare is proud to work with Apple to operate portions of Private Relay infrastructure.
In this post, we’ll explain how website operators can ensure the best possible experience for end users using iCloud Private Relay. Additional material is available from Apple, including “Set up iCloud Private Relay on all your devices”, and “Prepare Your Network or Web Server for iCloud Private Relay” which covers network operator scenarios in detail.
How browsing works using iCloud Private Relay
The design of the iCloud Private Relay system ensures that no single party handling user data has complete information on both who the user is and what they are trying to access.
To do this, Private Relay uses modern encryption and transport mechanisms to relay traffic from user devices through Apple and partner infrastructure before sending traffic to the destination website.
Here’s a diagram depicting what connection metadata is available to who when not using Private Relay Continue reading

Contribute to netlab: OSPFv3
Every other blue moon I get a question along the lines of “how could I contribute to netlab”. The process is pretty streamlined and reasonably (I hope) documented in Contributor Guidelines; if you want to get started with an easy task, try implementing OSPFv3 for one of almost a dozen devices (vSRX implementation by Stefano Sasso is a picture-perfect example):
