Class A networks have a 1-byte-long network part. That leaves 3 bytes for the rest of the address, called the host part. Class B networks have a 2-byte-long network part, leaving 2 bytes for the host portion of the address. Class C networks have a 3-byte-long network part, lea...
(Gbit/s), time-consuming fault detection results in the loss of a large number of packets. As such, the high reliability requirements of carrier-class networks cannot be met. To address this problem, configure BFD for OSPF to implement fault detection within milliseconds, maximizing OSPF ...

C 正确答案:C 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 ...
Class B networks use a default subnet mask of 255.255.0.0 and have 128-191 as their first octet. The address 172.16.52.63 is a class B address. Its first octet is 172, which is between 128 and 191, inclusive. Class C networks use a default subnet mask of 255.255.255.0 and have 192-...
/setclassid6 修改 IPv6 DHCP 类 ID。默认情况下，仅显示绑定到 TCP/IP 的每个适配器的 IP 地址、子网掩码和默认网关。对于 Release 和 Renew，如果未指定适配器名称，则会释放或更新所有绑定到 TCP/IP 的适配器的 IP 地址租用。对于 Setclassid 和 Setclassid6，如果未指定 ClassId，则会删除 ClassId...
The masks for traditional Class A, B and C networks are shown below in Table A-2 Table A-2 Standard IP Subnets Class Subnet Mask A 255.0.0.0 B 255.255.0.0 C 255.255.255.0 Comparing the masks above to the first chart, you can see that the 255s in a mask identify the...
IP地址分成5类:A类(Class A),B类(Class B),C类(Class C),D类(Class D)和E类(Class E)。其中A、B和C类地址是基本的因特网地址,是用户使用的地址,D类地址用于多目标广播的广播地址,E类地址为保留地址。IP地址的详细结构如图15-04所示。 图15-04 IP地址的组成 ...
●用PowerFlex4-Class HIM设定。 BOOTP-DHCP服务器的IP地址设定,PowerFlex 525与其他设备完全一样,这里不再讨论。 1.用RSLinx Classic设定变频器IP地址 通过RSLinx Classic链接软件浏览,右击PowerFlex 525设备,选中Module Configuration,如图2-62所示。 图2-62 选中PowerFlex 525模块组态 单击Module Configuration,进入模块...
