This forces reliance on coarse resolver data instead of precise user proximity, rendering standard triangulation ineffective for accurate edge server selection without ECS." } }, { "@type": "Question", "name": "How does Explicit Client Subnet improve traffic mapping accuracy?", "acceptedAnswer": { "@type": "Answer", "text": "ECS embeds a truncated client IP prefix directly into the DNS query payload. This allows authoritative servers to override resolver location signals and route traffic based on actual user subnet proximity rather than recursive resolver geography." } }, { "@type": "Question", "name": "What privacy risks arise from enabling ECS in DNS queries?", "acceptedAnswer": { "@type": "Answer", "text": "ECS leaks client network topology by exposing partial user identity to every authoritative server. This breaks traditional privacy boundaries where recursive resolvers usually shield end-user data from upstream infrastructure and third-party content providers." } }, { "@type": "Question", "name": "How many access networks does Akamai connect to for steering?", "acceptedAnswer": { "@type": "Answer", "text": "Akamai leverages subnet visibility to direct traffic across 1,200 connected access networks globally. This extensive connectivity allows dynamic steering decisions that prevent individual points of presence from becoming overwhelmed during sudden traffic spikes." } }, { "@type": "Question", "name": "What volume of global internet traffic relies on this steering model?", "acceptedAnswer": { "@type": "Answer", "text": "Operators use this DNS-centric visibility to manage approximately 30% of global internet volume daily. This massive scale requires precise routing to ensure content delivery reaches users via the nearest cache node without saturation." } } ] } </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">Akamai moves 15–a significant share of global internet traffic daily by relying on <strong>DNS-based content steering</strong> to map users to edge servers.</p>
