固定边界;

b. 地址划分错误.语法检查工具:http://www.nic.edu.cn/RS/oldnet.html 申请中的难点问题 以传统的1个C为固定边界划分子网将多个子网硬凑成1个C,例如: old-network: 166.111.1.0 255.255.255.0 YES

256 80/156/252 Dept Of Mechanics & Dept Of Electric power & Dept Of Economy Management & Dept Of Culture and Arts应该将每个系所用途的子网单独描述出来,譬如,子网大小实际上可能是:old-network: 166.111.1.0 255.255.255.128 YES

128 d/d/d Dept of Mechanicsold-network: 166.111.1.128 255.255.255.192 YES

64 d/d/d Dept of Electric Power old-network: 166.111.1.192 255.255.255.224 YES

32 d/d/d Dept of Economy Management old-network: 166.111.1.224 255.255.255.224 YES

32 d/d/d Dept of Culture and Arts将一个较大的子网硬拆分成多个C. 例如:> old-network: 166.111.2.0 255.255.255.0 YES

256 120/130/150 Library> old-network: 166.111.3.0 255.255.255.0 YES

256 200/250/253 Library子网大小应为/23,譬如子网大小实际上是:old-network: 166.111.2.0 255.255.254.0 YES

512 d/d/d Library 申请中的难点问题 old-network: 子网划分错误可能出现的错误:old-network: 166.111.3.0 255.255.254.0 YES

512 d/d/d Libraryold-network: 166.111.5.0 255.255.255.0 YES

256 d/d/d Library应修改为:old-network: 166.111.3.0 255.255.255.0 YES

256 d/d/d Libraryold-network: 166.111.4.0 255.255.254.0 YES

512 d/d/d Library 申请中的难点问题 network-plan:常见问题:?a. 没有按需分配地址;

b. 学生宿舍和教工宿舍信息不完整;
