) the Ifconfig (8) command is typically run at boot time to configure each interface on the host. Because the dial-up interface may be plugged in and out frequently (such as a slip link), the ifconfig must run in some way each time the line is switched on and off. How this process is done depends on the slip software used.(2) the Netstat (1) command provides the interface information on the system. The-I parameter prints out the interface information, and the-n parameter prints out the

Today, let's talk about the standard Internet communication protocol-TCP/IP protocol.This part of content may not be very understandable and abstract. It is a tough nut for beginners, but since it is a beginner, don't let everyone have any mental burden. No one is a genius, right? I will try my best to give you more ex

interfaces (multicast, broadcast, or anycast addresses). Each interface has a minimum of 32-bit IPV4 addresses, and there are typically several 128-bit IPV6 addresses.Both IPV4 and IPV6 support address formats that point to multiple network interfaces at the same time. IPV4 supports broadcast addresses and multicast addresses, but IPV6 only supports multicast addresses. Broadcasts allow one person to communicate with everyone, while multicast allows one person to communicate with multiple peopl

numbers for the site to allocate itself. This approach allows site administrators to compromise on the number of subnets and the number of hosts expected for each subnet, reducing coordination with other sites.It's like the school does not assign classrooms to each class, but instead throws the task to the college to deal with. The flexible compromise of the college was a slight solution to this vexed question. So what is subnet addressing? How does it work?One hours a day to write a blog is th

[TCP/IP details: Study Notes] IGMP: Internet Group Management Protocol

Internet Group Management Protocol (IGMP), which allows all systems on a physical network to know the multicast group in which the host is currently located. Multicast routers need this information to know which ports multicast data packets should be forwarded. IGMP is defined in RFC 1112. IGMP has a fixed message length and no data is available. The protocol f

ICMP is considered a part of the IP layer, which transmits error messages and other information that requires attention. ICMP packets are often used by the IP layer or higher protocol (TCP/UDP) (some error messages are returned to the user process ). ICMP packets are transmitted inside

If a host that receives the broadcast package finds that it meets the conditions, prepare an ARP packet containing your MAC address and send it to the host that sends the ARP broadcast, the broadcast host will update its ARP cache after obtaining the ARP package (that is, the place where the corresponding table of the IP-MAC is stored ).
