are separated by colons, for example: 08: 00: 20: 0a: 8c: 6d is a MAC address. The first six hexadecimal digits 08:00:20 represent the number of the network hardware manufacturer, it is distributed by the IEEE (istitute of Electrical and Electronics Engineers, Association of Electrical and Electronics Engineers), and the last three hexadecimal numbers 0a: 8c: 6D represents the serial number of a network product (such as a NIC) manufactured by the man

for each host is a fundamental feature of the IP routing mechanism. Doing so can greatly reduce the size of the routing table, for example, routers on the internet have only thousands of of the tables, and not more than 1 million of the table entries.4. Subnet addressingAll hosts are required to support subnet addressing. Instead of the IP

Reserved IP address AssignmentThe unification of IP addresses on the Internet is managed by an organization called the IANA (Internet Assigned Numbers Authority, internet network number distribution agency). Depending on the purpo

First, explain the concept of "intranet" and "Extranet": Intranet: That is to say the LAN, such as the school's local area network, the local area network each computer IP address in this local area network has the mutual opposite sex, is not repeatable. But the intranet IP in two LAN can have the same. Extranet: That is, the

static IP address of your Internet access to the NIC address of the recorded computer. The specific command is: ARP-s 192.168.0.4 00-eo-4c-6c-08-75 In this way, you can bind the static IP address 192.168.0.4 to the computer wit

: After logging to the proxy server, let the network administrator bundle the static IP address of your Internet connection with the network card address of the recorded computer. The specific commands are: Arp-s 192.168.0.4 00-eo-4c-6c-08-75 In this way, the static IP

is with IP conflict resolution This situation is mainly due to other computers under the router is also using your computer's IP address, resulting in IP address conflicts, there is no access to the Internet and so on. The main
