LAN Formation Successful 150 points

Line land rover supports not double port. Yes, you can separate and plug in. /

Not supported You can buy a switch.

Very simple.

1,800 computers, divided into 30 computer rooms, are grouped into a local area network, and the allocation scheme of the IP address of this local area network is written.

Hello, I am glad to answer for you, to assign a fixed IP to the local area network, you need to select the IP address segment according to the number of people, and then set the fixed IP on the router and each office computer and server; 1. Disable the DHCP function on the gateway or router, or leave only a small number of addresses for DHCP dynamic allocation; 2. Decide whether to use Class B or Class C addresses according to the number of PCs or servers that need to be accessed in the LAN; 3. Set the IP address mode to static for each PC in the LAN, use the static IP that can be assigned in turn, and set the IP address, subnet mask, and default gateway; 4. If the equipment in the LAN needs to access the Internet, you need to set one or two DNS server addresses.

Let's take a look at books like networking engineering, I learned it when I was in school and forgot it.

Summary. It is now necessary to divide the 1,000 machines of a department into local area networks, where the first local area network contains 500 computers, the second local area network contains 250 computers, and the third local area network contains 250 computers. If an address block assigned to the department requires each LAN to be in different network segments, assign an appropriate address block (including the network prefix) to each LAN and write out the broadcast address, subnet mask, and host address range for each LAN.

If an address block assigned to the department requires each LAN to be in different network segments, assign an appropriate address block (including the network prefix) to each LAN and write out the broadcast address, subnet mask, and host address range for each LAN. Hello dear, 1000 computers, divided into 4 subnets, 250 computers per subnet, mask use hope can help you.

What about the LAN's broadcast address, subnet mask, and host address range?

What about the LAN's broadcast address, subnet mask, and host address range? Hello dear, take the IP address and subnet mask as an example, calculate the network address, broadcast address, address range 1, convert the IP address and the subnet mask to binary numbers, the subnet mask is all 1 consecutive network address, the first 3 digits, that is, the network address in front of the thick line, and the host address in the back. 2. The network address part of the IP address and the subnet mask is calculated, and the final host address becomes 0, and the result is the network address, that is, the first IP address in the specified network segment.

Note that this address cannot be assigned to any computer. 3. If the network address part in the result of the above and operation remains unchanged, and the host address becomes 1, then the obtained is the broadcast address, which can also not be assigned to the client. A valid range of IP addresses in that network is:

1.On the first floor, a weak motor room is configured, a router and an aggregation switch (three floors, 24 ports are sufficient), and an access switch (two floors, 48 electrical ports) is added on each floor.

2.The router is connected to the operator (how to connect here, according to the service mode you choose), the aggregation switch is connected to the exit router, the floor is connected to the switch, and the access switch is connected to each terminal through the information module. Different VLANs and SVI addresses can be configured on the aggregation switch.

Links that converge to access can be in trunk mode, and different VLANs can be configured on the access switch and connected to different interfaces.

3.The network segment can be different for each floor and each VLAN.

4.With or without ** servers.

5. 1.Check whether the IP address configuration is correct, and if so, go to the second step. If the VLAN-SVI address of the host is pinged, go to the third step, and if it is not connected, check the aggregation switch and access switch. The address of the router's internal network interface, if ping, go to the fourth step, if not, check the router; 4.

Ping any address on the Internet; If not, check the router.

If I am a network administrator.

I will use the following options to assign IP addresses to these 50 Sparrow computers.

1. All static allocation, one by one to manually set a fixed IP address, which is conducive to IP, MAC binding, and port security. Fast troubleshooting and high safety in the later stage. It is suitable for fixed lead ports and fixed computers.

Class A. Available, Subnet Mask: , Gateway.

2. All adopt DHCP dynamic allocation, through DHCP server.

To quietly assign IP addresses to 50 computers, there is no need to manually set IP one by one, which is suitable for non-fixed terminal use.
