英文: Given that you have a class B IP address network range, which of the subnet masks below will allow for 100 subnets with 500 usable host addresses per subnet?中文: 给你一个B类地址,以下那个子网掩码允许支持100个子网,每个子网内可容纳500台主机。
Class B network: Everything before the second period indicates the network. Again using 203.0.113.112 as an example, "203.0" indicates the network and "113.112" indicates the device within that network. Class C network: For Class C networks, everything before the third period indicates the netw...
Class A: 255.0.0.0 Class B: 255.255.0.0 Class C: 255.255.255.0 Classless Subnetting (VLSM) Classless subnetting (VLSM) is a method of subnetting that allows for more flexibility in subnet design. VLSM does not use the three classes of IP addresses to determine the subnet mask. Instead, it...
A subnet mask that is used on an Internet Protocol version 4 (IPv4) class-based network. The subnet mask for Class A is 255.0.0.0. The subnet mask for Class B is 255.255.0.0. The subnet mask for Class C is 255.255.255.0. + 添加翻译 英文-意大利文字典 subnet mask predefinita A ...
Consider a Class B address, 172.16.0.0. By default, the Class B address 172.16.0.0 has 16 bits reserved to represent the host portion, thus it allows 65534 (216-2) valid host addresses. If network 172.16.0.0/16 is subnetted because it borrows three bits from the host portion, eight (23...

解析:Explanation:Using the 2n-2 formula for host addresses, 29-2 = 510 host address, so a 9-bit subnet mask will provide the required number of host addresses. If these 9 bits are used for the hosts in a class B network, then the remaining 7 bits are used for the number of network...
Not really a calculator, but more so a table containing all the subnets and how many usable addresses (Subnet Size - 2 for the network and broadcast address) Subnets Usable Addresses Subnet Mask Class A Class B Class C Class A Class B Class C Class A /8 255.0.0.0 1 16777214 /9 ...
Class B addresses have their first octet in the range 128 to 191 (binary address begins with 10). Class C addresses have their first octet in the range 192 to 223 (binary address begins with 110). The subnet calculator allows the use of a single subnet bit - for example, a class C ...
