While commercial DDoS mitigation services exist, they often come with high costs, vendor lock-in, and limited customization. BGP Flowspec (RFC 5575) offers a powerful, standards-based approach to distributed traffic filtering that can be deployed entirely with open-source software.</p> https://www.pistack.xyz/posts/2026-05-12-self-hosted-dns-rate-limiting-dnsdist-bind-rrl-unbound-guide/ Tue, 12 May 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-05-12-self-hosted-dns-rate-limiting-dnsdist-bind-rrl-unbound-guide/ <p>DNS rate limiting is a critical defense layer for any self-hosted DNS infrastructure. Without it, your recursive or authoritative servers become amplification targets in distributed denial-of-service (DDoS) attacks. This guide compares three leading approaches to DNS rate limiting: <strong>dnsdist</strong> from PowerDNS, <strong>BIND Response Rate Limiting (RRL)</strong>, and <strong>Unbound&rsquo;s built-in rate-limit</strong> feature.</p>
