Some NPM vendors started pairing DNS lookup records with flow data in order to separate business applications from non-business applications hosted on the same IP address. The problem is that many companies have several DNS servers spread out in far-reaching locations, and not all DNS vendors allow access to the logs.

Todays roundup blog post shares two exciting updates across our platform: our cross-platform 1.1.1.1 & WARP applications (consumer) and device agents (Zero Trust) now use MASQUE , a cutting-edge HTTP/3 -based protocol, to secure your Internet connection. Additionally, DEX is now available for general availability. Why MASQUE?

Additional network resilience mechanisms Successfully routing a packet over the internet from its source to its destination is not trivial. Message integrity and guaranteed delivery with TCP/IP Because IP does not require acknowledgments from endpoints, it does not ensure delivery; therefore, it is considered an unreliable protocol.

While the internet and the web are inherently decentralized, mainstream applications built on top do not have to be. We're still waiting on Pied Piper to deliver the decentralized internet. Typically, applications today—Facebook, Salesforce, Google, Spotify, etc.—are —are all centralized. That wasn't always the case.

In simple terms, Border Gateway Protocol (BGP) is the protocol that routes traffic on the Internet. Each BGP speaking organization is assigned an Autonomous System Number (ASN) that identifies them on the Internet. During last week’s attack, the attacker was redirecting traffic that belonged to Amazon’s Route 53 DNS servers.

MAC address in the data link layer of a packet capture Moving up the stack, at the network and transport layers, is a much more granular source of information, the TCP/IP stack. In Figure 3 and Figure 4, we can see a packet capture of a MacBook laptop initiating a TCP connection to a remote server.

An engineer standing in front of a console today stares at the traffic moving from their on-prem data center up and out to a CASB, receiving DNS responses from a cloud-provided DNS service, and then on through an ephemeral microservices architecture in a public cloud. And this, of course, is just to reach the front end.

Distributed denial-of-service (DDoS) attacks have been a continuous threat since the advent of the commercial Internet. The victim can update DNS to point at a different IP address in an attempt to get their application back up. Introducing Kentik’s New BGP Flowspec Support.

And when we find that, we’ll want to see interface errors, DNS response times, TCP retransmissions from container resources, and so on, all in a time series to identify what is causing that latency. Today, when we learn that an application is slow, we need to be able to pinpoint precisely where in the path latency is happening.

These datacenters each have multiple BGP Internet peerings to facilitate resilience and performance. Service components and dependencies are spread across datacenters, the cloud, and the Internet, and applications involve increased east-west traffic flows, which makes end-to-end performance heavily reliant on predictable network behavior.
