What is the 169.254.x.x IPv4 address?
Post Views: 359 The 169.254.x.x IPv4 address is called the APIPA address. APIPA stands for Automatic Private IP Addressing. It’s a fallback mechanism built into Windows (and most modern operating systems) to give your network interface a “link local” address when it can’t get one from a DHCP server. The APIPA IPv4 Addresses are any
The TLS 1.2 Protocol Ladder
Post Views: 466 I provide this information for reference when examining TLS in Wireshark. The TLS 1.2 protocol ladder (also called the TLS handshake ladder) describes the step-by-step sequence of message exchanges between a client and server as they negotiate a secure, encrypted connection. Think of it as a “ladder” where each side alternates rungs
What is the Adapter for loopback traffic capture in Wireshark?
Post Views: 507 Using a loopback adapter (also called a local loopback interface) for packet capture in Wireshark allows you to capture traffic that stays within your own computer — for example, packets exchanged between local applications via localhost or 127.0.0.1. Normally, this traffic never reaches a physical network interface, so a loopback capture is

MPLS – The Most Secure without Encryption
Post Views: 789 Let’s just start right out and say: contrary to the scare tactics made by some, that MPLS traffic has been exposed by the providers that operate MPLS, there has never been any validated evidence that such a breach has indeed ever occurred, other than some alleged errors in configuration. MPLS operates between
MPLS – the Greatest Service Provider Technology of All Time
Post Views: 2,056 MPLS (Multiprotocol Label Switching) is often regarded as one of the most elegant service provider networking technologies after TCP/IP itself because it solved several big problems introduced in the late 1990s (and I got to be part of that): For service providers, this was game-changing. Many argue that without MPLS, the explosion
Can ChatGPT 5 analyze PCAP’s?
Post Views: 2,913 I am a ChatGPT subscriber to the basic (not PRO) service. I saw the following post on LinkedIn and was fascinated: Think about the implications. You don’t need to know how to use Wireshark other than to do a capture. You certainly don’t need to know how to troubleshoot packet captures as
