تندرج النُظم ذاتية التحكم عادة في ثلاث فئات:
يرمز له بـ (ASN) ويعمل الرقم كمعرف للنظام المستقل ويُستخدم عند تبادل معلومات التوجيه مع الأنظمة ذاتية التحكم الأخرى، وتتوفر بتنسيق 16 بت و32 بت، بحيث يكون لكل منطقة سجل أرقام إقليمي على الإنترنت يسجل أرقام النظم ذاتية التحكم، وفيما يلي المناطق الخمس والمساحة التي تحتفظ بها كل منطقة:
