Internet protocol specifications are instructions designed for engineers to build things. Any reasonably skilled engineer should be able to take a specification and produce a performant, reliable, and secure implementation. Cloudflare has supported QUIC on our global network in some shape or form since 2018.

Most Azure users use hub-spoke network topology. DNS servers are usually deployed in the hub virtual network or an on-prem data center instead of in the Cloudera VNET. AKS API server private endpoint—the public DNS zone stores the private IP of that service. Most users have restrictions on firewalls for wildcard rules.

The attack requires introducing a rogue DHCP server to the local network. This is not easy on well-maintained networks, that use trust zones and DHCP snooping features to prevent this attack vector. In the case presented in the article, the malicious DHCP server poisons the routing table of its neighbor on the local network.

Intel has developed and sold classic Ethernet Network Interface Cards (NICs) for a long time, but many might not be as familiar with their product offerings in the SmartNIC and more advanced NIC categories. There were two features in the IPU that are something infrastructure engineers should know about.

To support the billions of people around the globe using our technologies, we need to be confident that every server — in every data center — knows and agrees what time it is, as accurately and precisely as possible. The more servers there are between endpoints, the more important synchronization is. A microwave keeps time on-device.

PTP’s predecessor, Network Time Protocol (NTP) , provided us with millisecond precision, but as we scale to more advanced systems on our way to building the next computing platform, the metaverse and AI, we need to ensure that our servers are keeping time as accurately and precisely as possible.
