IP 地址列表: 121.50.2.* (121.50.2.0 - 121.50.2.254)
這是第壹個字節為121,第二個字節為50,第三個字節為2,第四個字節在0 - 255之間的IP地址列表,表示為121.50.2.* (121.50.2.0 - 121.50.2.255)。
這個IP地址列表中包含256個IP地址,我們以其中壹個IP地址121.50.2.1為例,來描述這個IP的屬性:
但這只是其中1個IP地址的例子,並不代表這個列表中所有的IP地址都有同樣的屬性,如果需要了解其它IP和更詳細的IP地址段信息,請點擊下面列表中的標題鏈接。
二進制、十進制和十六進制的 IP 地址說明 IP 地址類別 A/B/C/D/E 和網絡 ID、主機 ID 的說明內容:
2. A類IP地址列表
A類IP地址是指:在IP地址的四段號碼(例如:字節1.字節2.字節3.字節4)中,第壹段號碼(字節1)為網絡號碼,剩下的後三段號碼(字節2.字節3.字節4)為本地計算機的號碼。 如果用二進制表示IP地址的話,A類IP地址就由1字節的網絡地址和3字節主機地址組成,網絡地址的最高位必須是'0'。 A類IP地址範圍:1.0.0.0 ~ 127.255.255.255,可用IP地址範圍:1.0.0.1 ~ 127.255.255.254。 A類IP地址中網絡的標識長度為7位,主機標識的長度為24位,A類網絡地址數量較少(2 ^ 7 - 2 = 126個),可以用於容納1600多萬計算機的大型網絡(2 ^ 24 - 2 = 16777214個)。 如果您需要了解A類IP段更詳細的IP地址信息,請點擊A類IP地址列表中的標題鏈接。
