subnet mask for single ip

the limited broadcast address ). * "0" Address According to the TCP/IP protocol, all the "0" Network numbers are interpreted as "local" networks. * Return address Class A network address 127 is a reserved address for network software testing and communication between local processes. It is called loopback address ). WhateverProgramOnce data is sent using the return address, the protocol software returns immediately without any network Transm

1. How many subnets will be generated The X power of 2-2 (X represents the mask bit, that is, the part of the binary system that is 1. In the current network,-2 is no longer required and can be used in all, however, you need to add the corresponding configuration commands. For example, you can use all the commands by adding the IP subnet zero command to the Cis

hosts in the same network segment are not communicating, the host sends the data to the gateway, which is then forwarded by the Gateway.In order to differentiate between these two situations, the computer that communicates is required to obtain the network segment portion of the remote host IP address to make a judgment.? If the source host's network address = The destination host's network address, the communication between the same network segment

network. These two IP addresses are reserved by TCP/IP and cannot be assigned to the host. In addition, the first subnet 192.168.10.0-31 and the last subnet 192.168.10.20.- 255 are also retained and cannot be used. The reason is that the network address of the first subnet

networks.4. Class DClass D addresses start at 111 0. This represents a eight-bit group from 2 2 4 ~ 2 3 9. These addresses are not used for standard I P addresses.Instead, a Class D address refers to a set of hosts that are registered as members of the multicast team. Multicast teams and emailThe allocation list is similar. Just as you can use the Assign list to publish a message to some people, you canMulticast addresses send data to some hosts. Multicast requires a special routing configurati

the need to request a purchase.Subnet Mask:The subnet mask is not an address, it is used to determine which part of an IP address is the network ID, which part is the host ID, the portion of a continuous 1 represents the network ID, and a continuous portion of 0 represents the host ID. For example, the first 24 bits of Class C network are the network number and
