  2. Overview • Background • The problem • APNIC Resource Quality Assurance • Scope • Challenges • Strategy

  3. Background • IP address gets filtered for various reasons • Bogon • Bad behaviour • Security/access policies • Most prevalent form of IP address filters • Route filtering • Application filtering, esp. Mail • Firewall filtering

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 The Problem • Legitimate internet traffic fails to reach the destination due to: • Outdated filters • Outdated black list / bogon list reference • RIR blamed for allocating ‘bad’ blocks • Situation worsens as IPv4 depletes • More bad blocks get uncovered • Prefix gets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

  5. APNIC Resource Quality Assurance • APNIC: more proactive, long-term strategy • Combined effort • Collaboration • Education • Whois Database quality • Establish procedures for prefix testing and filter removal

  6. RQA Strategy • Community awareness campaign • Build relationships with reputable organizations that maintain bogon/black list • Keep the Whois Database accurate • Actively remind resource holders to update their data

  7. We need your help, so let’s work together Thank you frank@apnic.net
