أغلبنا وأن لم يكن كلنا قد قام بدراسة الـIPv4 Header الموجود في الطبقة الثالثة Network Layer ولاحظ وجود خانة تدعى Protocol وهي عبارة عن 8 بت يتم فيها كتابة الرقم الخاص بالبروتوكول المستخدم لذا ومن باب حب الأستطلاع توجهت إلى موقع أيانا وقمت بأعداد جدول يوضح رقم ونوع كل بروتوكول يتم كتابته في هذه الخانة وأحببت أن أشارككم أياه

وآخيرا أحب أن أضيف أن خانة الـProtocol موجودة أيضا في الـ IPv6 لكن بمسمى آخر وهو Next Header أتمنى أن الموضوع قد أفادكم ودمتم بود
