CIDR replaced this rigid model to allow flexible sizing between huge ranges and small subnets." } }, { "@type": "Question", "name": "How does announcing too many routes hurt the shared BGP system?", "acceptedAnswer": { "@type": "Answer", "text": "Individual networks announcing extra routes impose a real cost on every other BGP speaker globally. This behavior transforms the shared routing commons into a bloated ledger of unnecessary data." } }, { "@type": "Question", "name": "What specific strategy does the CIDR Report use to fix noisy networks?", "acceptedAnswer": { "@type": "Answer", "text": "The report uses transparency and naming-and-shaming to nudge noisy speakers into better behavior.
