Merabalar;
Herkes durmadan ayni MAC adresi diyor. Abdullah Bey ayni MAC adresi demiyor.
MAC adreslerinin belirli bir kismi ayni basliyor diyor. MAC adresleri 48
bitten olusur.
Bunun ilk 24 bitlik kisimlar IEEE tarafindan ureticilere satilir.(verilir).
Dogal olarak
3Com bir ethernet karti aliyorsaniz ve ayni yil uretilmis veya ayni model
bir seri ise
genel olarak bu ilk 24 bit ayni olabiliyor. Kalan 24 bit ise vendor
tarafindan yine uniq olarak
belirleniyor.
Asagidaki dosyayi incelerseniz sorununuzu cozebilirsiniz...
Iyi Calismalar,
Aydin KOCAK.
----------------------- MAC Kisimlarini kendinize uygun
degistirebilirsiniz.-----------
