Research shows over 90% of captured scan packets were ICMPv6 echo requests targeting larger, actively advertised address blocks instead." } }, { "@type": "Question", "name": "What volume of unsolicited traffic did the proactive /32 telescope deployment successfully capture?", "acceptedAnswer": { "@type": "Answer", "text": "The large-scale deployment collected over 600 million unsolicited IPv6 packets during its operational period. This massive dataset proved that broadcasting decoy routes drives detection volume far higher than passive listening." } }, { "@type": "Question", "name": "How does announcing BGP routes change visibility compared to relying on passive darknet monitoring?", "acceptedAnswer": { "@type": "Answer", "text": "Broadcasting BGP routes transforms silent blocks into visible targets that scanners actively probe for hints. Without these signals, quiet networks attract negligible traffic while active lures reveal diverse scanner sources globally." } }, { "@type": "Question", "name": "What specific packet type dominated the traffic observed in the large-scale IPv6 telescope study?", "acceptedAnswer": { "@type": "Answer", "text": "Over 90% of the captured scan packets consisted of ICMPv6 echo requests targeting the decoy prefixes. This indicates scanners primarily use basic connectivity checks rather than complex application-layer probes during initial reconnaissance phases." } }, { "@type": "Question", "name": "How many distinct Autonomous System Numbers were identified as sources in the telescope dataset?", "acceptedAnswer": { "@type": "Answer", "text": "The collected traffic originated from nearly 2,000 different Autonomous System Numbers across the global internet. This wide distribution confirms that scanning activity is no longer dominated by just a few specific sources." } } ] } </script> <!-- /wp:html --> <!-- wp:html --> <style> .faq-section { margin: 24px 0; padding: 24px 0; border-top: 2px solid #e5e7eb; } .faq-section-title { color: #1a1a1a; font-size: clamp(1.2rem, 3vw, 1.4rem); font-weight: 700; margin-bottom: 24px; text-align: center; } .faq-item { background: #fff; border: 1px solid #e5e7eb; border-radius: 8px; margin-bottom: 12px; overflow: hidden; transition: all 0.3s ease; } .faq-item:hover { border-color: #2563eb; box-shadow: 0 4px 6px rgba(0,0,0,0.05); transform: translateY(-2px); } .faq-question { background: #f9fafb; padding: 12px 16px; cursor: pointer; position: relative; transition: all 0.3s ease; border: none; width: 100%; text-align: left; font-family: inherit; display: block; } .faq-question:hover { background: #e8f0fe; } .faq-question-text { color: #1a1a1a; font-size: 1rem; font-weight: 600; line-height: 1.5; margin: 0; padding-right: 2rem; display: inline-block; } .faq-answer { max-height: 0; overflow: hidden; transition: max-height 0.4s ease, padding 0.4s ease; padding: 0 16px; } .faq-item.active .faq-answer { max-height: 1000px; padding: 0 16px 16px; } .faq-answer-text { color: #4b5563; font-size: 1rem; line-height: 1.7; margin: 12px 0 0; } </style> <script> (function() { function initFAQ() { var qs = document.querySelectorAll(".faq-question"); for (var i = 0; i < qs.length; i++) { qs[i].addEventListener("click", function() { var item = this.closest(".faq-item"); var wasActive = item.classList.contains("active"); var allItems = document.querySelectorAll(".faq-item"); for (var j = 0; j < allItems.length; j++) { allItems[j].classList.remove("active"); } if (!wasActive) item.classList.add("active"); this.setAttribute("aria-expanded", String(!wasActive)); }); } } if (document.readyState === "loading") { document.addEventListener("DOMContentLoaded", initFAQ); } else { initFAQ(); } })(); </script> <!-- /wp:html --> <!-- wp:paragraph {"className":"std-text"} --> <!-- /wp:paragraph --> <!-- wp:paragraph {"className":"std-text"} --> <p class="std-text"><a href="https://datatracker.ietf.org/doc/html/rfc8200" target="_blank" rel="noopener noreferrer">IPv6</a> scan traffic surged <strong>one hundred times</strong> between 2022 and 2023.
