MAC Address

Last updated at Posted at 2017-05-15

MAC Address(Media Access Control Address)

各NIC(Network Interface Card)に付与される世界で区別できるキー
総6バイト(48ビット)として構想される

  • 例 : 00-00-00-11-11-11
  • 前から3バイトは各ベンダー社に付与される固有コード
  • 後3バイトは各ベンダー社がNICに付与するコード
    NICを交換すると変わるが、最近はマザーボードに一体型のパタンがあるため
    マザーボードが変わるとMACアドレスが変わる場合が多い
