Maybe. 😄<br/><br/>I put together a deep dive into how Ethernet actually works, going well beyond the usual “Layer 2 uses MAC addresses” explanation.<br/><br/>It covers:<br/><br/>• Ethernet frame structure &amp; EtherType<br/>• MAC learning, CAM tables &amp; switching<br/>• ARP &amp; ARP spoofing<br/>• VLANs &amp; 802.1Q<br/>• STP, loops &amp; broadcast storms<br/>• MAC vs IP across routed hops<br/>• MTU, MSS &amp; jumbo frames<br/>• PHYs, duplex &amp; auto-negotiation<br/>• Wireshark, TSO/GSO/GRO &amp; checksum offloading<br/>• Virtual Ethernet, VXLAN &amp; modern data centers<br/>• Practical Ethernet troubleshooting<br/><br/>Basically, Ethernet from the wire all the way up to modern virtualized networks, with the details that are usually glossed over.<br/><br/><a href="https://thecybersecguru.com/networking/how-ethernet-works/">https://thecybersecguru.com/networking/how-ethernet-works/</a><br/><br/>If you&#39;re learning networking, doing security work, troubleshooting packets, or preparing for CCNA, this is meant to be a reference you can come back to.<br/><br/>#Ethernet #Networking #InfoSec #Cybersecurity #CCNA #Wireshark<br/> <img src="https://media.infosec.exchange/infosec.exchange/media_attachments/files/117/097/817/095/082/031/original/fc506b08fbf03ef1.png"> <br/> 2026-08-15T05:14:56Z https://njump.me/nevent1qqsrssu8th37surp8fvcm09nem2xu0mjhhq4u5saw92hncgduayhanqzypzt7l5cj2kclnlqg85y4eutvml93yz2796d4mxmaqdgxt6jlrdfvxu70xf Dead Internet Theory is getting harder to dismiss.<br/><br/>Cloudflare says automated systems now account for more web requests than humans in its measurements. The company is also forecasting that machine-generated traffic could become roughly 1,000× human traffic within five years if current trends continue or as they put it &#34;Humans may become a rounding error on the internet&#34;.<br/><br/>That doesn&#39;t mean 57% of internet users are bots. Web requests and human users are very different measurements.<br/><br/>What is changing is the amount of work being done by machines: crawlers, AI training systems, search agents, autonomous agents, recommendation systems and automated fraud infrastructure.<br/><br/>AI is also starting to change the content layer itself. A growing amount of new web content is AI-generated or AI-assisted, while AI systems are simultaneously crawling that content for training, search and retrieval.<br/><br/>The conspiracy theory that humans have been replaced by bots isn&#39;t supported by the evidence.<br/><br/>The shift toward a web where machines increasingly crawl, generate, rank and consume information is.<br/><br/>I went through the bot-traffic data, AI crawler activity, AI-generated content research and the latest Cloudflare projections:<br/><br/><a href="https://thecybersecguru.com/analysis/dead-internet-theory/">https://thecybersecguru.com/analysis/dead-internet-theory/</a><br/><br/>#infosec #cybersecurity #AI #bots #OSINT 2026-08-09T16:49:48Z https://njump.me/nevent1qqsfqap448ps550ytl78kn9t5sj0mem400pdez245tcl6ktjgsfj6yczypzt7l5cj2kclnlqg85y4eutvml93yz2796d4mxmaqdgxt6jlrdfvhpwa33 🚨 New WordPress Core vulnerability.
