IPv4
Address
- 網路遮罩(network mask):將網路位元設為1,主機位元設為0,由左(network; 1)至右(host; 0),不會出現1、0交錯。
- 網域位置(network address):進行網域(Network Domain)辨識用的,將主機(host)位元值全設為0。
- 廣播位置(boardcast address):對某網域所有節點(node)執行廣播運用的位置,將主機(host)位元值全設為0。
- 主機位置(host ip):原本網域經過network mask後的位置 (=network address)。
- host ip range:從網域位置+1到廣播位置-1。
例題1:1.2.3.129/25,請問這個IP位址所在的網路位址為何?所在的網路廣播位址為何?所在的網路IP address Range?Network Mask?

網路規劃
例題4:在200.100.0.0 網域下,以CIDR 進行網域分配,若200.100.2.0~200.100.5.0,200.100.10.0~200.100.11.0 已經用去,公司甲、乙、丙、丁分别需要1000、2000、100、500 個網點,請填寫各公司IP 位址範圍、網域位址、廣播位址、network mask,位址分配盡量往前安排為原則。
