The number of interface that is UP/DOWN in Protocol is 协议的UP/DOWN状态以及处于不同状态的接口数目。 Interface 接口类型和接口编号。 IP Address/Mask 接口的IP地址/子网掩码。 Physical 接口的物理状态。可能出现的物理状态有: Up:接口处于正常启动的状态。其中(l)表示在接口上设置了环回功能。
A list of matching routes is compiled. The route that has the longest match (the route with the largest number of bits that match the destination IP address) is chosen. The longest matching route is the most direct route to the destination IP address. If multiple matching entries are found...
An IP address consists of 32 bits. Instead of expressing IPv4 addresses 32 bits at a time using binary notation (Base2), it is standard practice to segment the 32 bits of an IPv4 address into four 8-bit fields calledoctets. Each octet is converted to a decimal number (base 10) from ...
16 bits IPv4 software maintains a counter in the storage device to record the number of IP datagrams. The counter value increases by 1 every time a datagram is sent, and is filled in the identification field. Flags 3 bits Only the rightmost two bits are valid. The rightmost bit indic...
It specifies the number of bits that comprise the IP address prefix. The prefix length must be preceded by a forward slash (/). The range can be from 0 to 32. ip-address - IP address of the next hop that can be used to r...

The text form of the IPv4 address isnnn.nnn.nnn.nnn, where 0<=nnn<=255, and eachnis a decimal digit. Leading zeros can be omitted. Maximum number of print characters is 15, not counting a mask. 128 bits long (16 bytes). Basic architecture is 64 bits for the network number and 64...
4 bits IPv4 首部长度,1 个单位代表 4 个字节,在没有选项的情况下,IPv4 首部长度为 5,即固定长度 20 字节(从 version 到 destination IP address),报头长度必须是 4 字节的整数倍,如果不是,需要填充 PAD 补 0 凑齐。 PAD Type of Service - 服务类型 ...
Local networks with large numbers of hosts are sometimes divided into subnets. If you choose to divide your network into subnets, you need to assign asubnet numberfor the subnet. You can maximize the efficiency of the IPv4 address space by using some of the bits from the host number part ...
The great increase in the number of devices connected to the Internet was not predicted at the time of creation the IPv4 protocol. Due to the fast growth of the Internet, the problem of the IPv4 addresses space exhaustion has app eared. Different technologies and solutions, such as NAT and ...
