the address type to be converted, and 0x0800 is the IP address, the length of the following two addresses is 6 and 4 (bytes) for the ethernet address and IP address respectively. The op field is 1, indicating the ARP request, and the OP field is 2, indicating the ARP response. The process of the Address Resolution Protocol is as follows: Iv. RARP (Reverse Address Resolution Protocol) The opposite of ARP is mainly used to obtain the IP address of a diskless workstation, as shown in. 5. ICMP

Common ping command protocols in the Network Network Protocol Network Firewall Router ICMP is the abbreviation of "Internet Control Message Ptotocol" (Internet Control Message Protocol. It is a sub-Protocol of the TCP/IP protocol family. It is used to transmit control messages between IP hosts and routers. A message c

ICMP is the so-called Internet Control Messaging Protocol (PROTOCOL), which is commonly used to transmit error messages and other information that should be noted in the network. ICMP is generally considered to be the same level as the IP protocol, IMCP packets are usually used by IP layer or higher level protocol (such as TCP or UDP), ICMP for the internet and other ip-based network based on the normal ope

This article describes the first example: five simple TCP Network service protocols, including Echo (RFC 862), Discard (RFC 863), Chargen (RFC 864), Daytime (RFC 867), Time (RFC 868), and time The client of the Protocol. The functions of each agreement are as follows: * Discard-discard all data received; * Daytime-service-side accept connection, send the current time as a string, and then actively disconn

Get host address information In Java we use the InetAddress class to represent the destination network address, including the host name and numeric type address information, and the InetAddress instance is immutable, and each instance always points to an address. The InetAddress class contains two subclasses, corresponding to the two version of the IP address: Copy Code code as follows: Inet4address Inet6address We know from

To increase internal security, you need to filter the external connections of the client. Although it is not easy to try to filter customers' connections, once you know which port your server is listening to, you can know which port your customer is trying to connect. Developing an access list for a customer connection is determined by under
