Subnetting subnets with subnet masks

IP addresses are classified into five categories--------------------------------------------------------------------------------------------------------------- ----------------------------------------------------the meaning of the subnet mask and subnetting according to the subnet maskThe subnet mask is used to divide subnets. For example, a Class A network can hold 16777214 hosts. However, in practice, it is impossible to use a class A network only f

addresses: ","Broadcast address: ""quickly divide subnets to determine IPLet's take example 2 for example:The topic requires that we divide the network address into subnets that can accommodate 101/54/2 hosts. Therefore, we need to determine the host location, and then determine the network bit based on the host bit, and finally determine the detailed IP address.① determining the host bitSet the number of hosts that you need to be

CCNA Cisco subnetting (compute and assign addresses using VLSM)

LAN.WANThe last network segment is a WAN connection and requires 2 host addresses. Support WAN links with just 2 primary seats. 2^2-2 = 2.This leaves 8 bits to define the local subnet address. The next available address block is representation:10101100.00010000.0000010.11000000Mask: 30 bits in binary:11111111.11111111.1111111.11111100The IPV4 host address range provided is: to, broadcast address is 17

IP address partitioning type and subnetting

application, a company applied for a public network, such as, but the company has two groups, a group of the number of hosts is 6, the number of hosts in the other group is 4, and do not want the two groups of hosts to communicate with each other, if you apply for a public network , the cost is too high, so it is necessary to divide this network into multiple subnets. The subnet is divided by the first m bits in the host bit in the network address and the network address bits as th

Subnetting with CIDR (slash plus number representation vs. IP) (improved)

mask calculation. Network ID Results We all know that the network ID part is unchanged, the host ID portion becomes 0, then in the calculation of the network ID, first look at how many bits in the subnet mask to represent the network, corresponding to the IP address conversion to binary only the previous few, such as 19, the network ID altogether 19 bits, then the network ID the first two bytes is 192.168.x.0 to change the third byte. So how do you quickly calculate the value o

Understanding of computer network address, host address, subnet mask, network segment, subnetting

subnets will need to occupy 1 bits of the original host identity bit. At this point the network number bit becomes 22 bits and the host label becomes 7 bits. Similarly borrowing 2 host bits can divide a class C network into 4 subnets ... How did the computer know if the network was divided into subnets? This can be seen from the subnet mask. The subnet mask is as 32bit as the IP address, and the subnet mask is determined by using "1" for all corresponding bits that identify the network number i

"IP layer Packet Forwarding process" in the case of subnetting, packet forwarding algorithm.

First, a sample from a Shehiren teacher's book is referenced:Host H1 the process of sending packets to H2:First, with the subnet mask in the subnet: and target host H2 IP address: and get network number: Obviously this does not match the network number of Subnet 1: datagram is then forwarded by the default route R1 Subnet 1. At this point, R1 will look for its own routing table. Think of the host address and subnet mask of the H2, and whe
