The Problem
  • Legitimate internet traffic fails to reach the destination due to:
    • Outdated filters
    • Outdated black list / bogon list reference
  • RIR blamed for allocating ‘bad’ blocks
    • Situation worsens as IPv4 depletes
      • More bad blocks get uncovered
      • Prefix gets recycled
