What is the binary equivalent of the decimal number 192?十進位數字 192 的二進位表示法是什麼？
You have subnetted your 192.168.36.0 network address with a 255.255.255.240 mask. How many subnets and hosts per subnet are available?你使用 255.255.255.240 遮罩對 192.168.36.0 網路位址進行子網路劃分。有多少個子網路，每個子網路有多少台主機可用？
How many valid host addresses are available for each subnet after subnetting network 192.168.0.0/24 by borrowing two host bits?借用 2 個主機位元對網路 192.168.0.0/24 進行子網路劃分後，每個子網路有多少個有效主機位址可用？
You are designing an IPv4 addressing scheme for a branch office. The branch office is assigned to the 172.16.32.0/25 subnetwork, so you have one subnet (172.16.32.0) with 126 host addresses available to you. However, you can see from your design branch office topology that the largest LAN will only require 11 host addresses. If you want to avoid wasting address space and allocate addresses efficiently, you will need to subnet your subnetwork further, which means applying the VLSM. Which subnet mask should you use to achieve the desired scheme?你正在為分公司設計 IPv4 定址方案。該分公司被指派 172.16.32.0/25 子網路，因此你擁有一個子網路（172.16.32.0），可用主機位址有 126 個。不過，從你的分公司設計拓樸中可以看出，最大的 LAN 只需要 11 個主機位址。若你想避免浪費位址空間並有效率地分配位址，就需要進一步劃分子網路，也就是套用 VLSM。你應該使用哪個子網路遮罩來達成所需的方案？
