A problem with the setting of the subnet mask of the router and the LAN to which it is connected

Setting: Route A is the primary route, and Route B is the slave route!

First, set the WAN port status of Route A to PPPoE dial-up status, and then fill in the ADSL dial-up and password.

Second, set the IP address of the LAN port of Route A to the IP segment of the LAN port to the network segment mask.

Third, set the LAN port IP of route B to the LAN port IP segment to the network segment mask, set the WAN port status of route B to static IP, and set the IP address to the mask of the gateway.

Fifth, connect the WAN port of Route B and any LAN port of Route A with network cables.

Through this method, the router can be connected to the router to achieve the purpose of expanding the router connection port on the LAN.

Routers use the longest match lookup route, and taking a look at the routing table of your PC will help you understand how the router works.

The PC also has a routing table, use route print to view, the gateway address corresponds to a default route, that is, the route where the destination address and mask are both the route, and when other routes do not match, this route will be taken.

The subnet mask on the PC should ideally be the same as on the router. If it's longer than the one on the router, you won't be able to access other PCs on the LAN if they don't share the same network segment as you.

If you don't have a Layer 3 switch.

The settings of the subnet mask on the PC need to be the same as the settings on F0 0 on the router.

The subnet mask is OK by default.

Stuffy, the subnet mask is calculated, how to calculate it, you can go to the ** to check, but the general gateway is the same, the submask should be the same, the second question is not known.

Taking the nanohail win7 system as an example, the method of setting the IP and subnet mask is as follows:

1. Find the network on the desktop of the first computer, right-click on the network icon, select Properties and click.

2. After entering the property, it will bounce to the interface in the following figure, and click on the local connection.

3. Click Properties after entering the local connection.

4. After entering the properties, select Protocol Version 4, and double-click the left mouse button to enter.

5. After entering, choose to use the IP address below, and then you can enter your IP address and subnet mask.

Set the hidden router subnet mask.

The error is caused by a setting error, and the solution to the square lead hall is as follows:

1. Enter the password to log in to your router management page.

2. Then click 'Internet Settings' on the page.

3. Here, mine automatically obtains IP, which is a commonly used broadband Internet access method, and this method does not need to set a subnet mask.

4. To change the way you access the Internet, we can click on the drop-down box above Huaiwang.

5. In the drop-down box, select 'Fixed IP address.'

6. So we need to enter the IP address here.

Subnet mask. Which bits identify the subnet in which the host is located, and which bits identify the host's bitmask. The subnet mask cannot exist on its own, it must be used in conjunction with an IP address.

The subnet mask has only one function, which is to divide an IP address into a network address.

and the host address.

A subnet mask is a 32-bit address that is used to mask a portion of an IP address to distinguish between network and host identities and to indicate whether the IP address is on a local area network or a remote network.

Provides a unified address format that masks physical addresses by assigning a logical address to every network and every host on the Internet.

differences. Default gateway.

creates a default path bucket change. A host can have multiple gateways. The default gateway means that if a host can't find an available gateway, it packets it.

The packet is sent to the gateway specified by default, and the gateway processes the packet.

The gateway used by the host is generally the default gateway. The default gateway for a computer is something that Shen Feng cannot specify casually, it must be specified correctly, otherwise a computer will send packets to a computer that is not a gateway, and thus cannot communicate with computers on other networks. There are two ways to set the default gateway: manual setting and automatic setting.

What the subnet mask does:

An IP address must belong to a certain network, or subnet. The subnet mask is used to specify the network address of a certain IP address, in other words, it is used to divide the subnet.

How to set the subnet mask:

1.To get started, open Control Panel, Network & Internet, and then turn on Network Connections.

2.Set the subnet mask as follows, the default subnet mask <>

Hello, dear <>

To divide a device with an IP address into two subnets, you can use the first 24 bits (i.e., the first three digits) as the network address and the last 8 bits (i.e., the last number) as the host address. 2.The value of the subnet mask is determined based on the number of bits of the network address and host address.

For the above example, the network address is the first 24 bits and the host address is the last 8 bits, so the value of the subnet mask is where the first three digits are 255 for the network address and the last number is 0 for the host address. 3.Configure the subnet mask in the device's network settings.

How to do this varies from device to device, and you can find the configuration options for the subnet mask in the network settings or network configuration. Set the subnet mask to the calculated value above. Dear, the above questions have also been answered for you, if you have other questions, please continue to ask, if not, please give a thumbs up!

Wishing you: a happy life and all the best! <>

Class A IP, default.

To mask is. Class B self-IP, the default mask is.

Class C IP, the default mask is.

Generally speaking, the corresponding IPs are Class A and Class B IPs

are subnetted.

All dao1 on the left is the network bit, and all zero on the right is the host bit.

For class A, 2 is divided into 2 to the 11th power, (network bit 11) and for class B, 2 is divided into 3rd power subnets (network bit 3).

Whether it is a baib address, no.

DU is based on subnet.

The mask to distinguish zhi is based on the IP address itself. After the ABC address in the DAO is subdivided, the mask can be set to. The number of subnets included in this mask is determined based on the original addresses before the subnets are divided, but the number of addresses in each subnet is determined at 512.

The mask is 23 bits, and the last bit of the third 8 bits is used as the host.

bit du, so the host bit is total.

9 bits. There are 128 DAOs to the 7th power of zhi2, and the number of hosts in each subnet is 2 to the 9th power minus 2, which is equal to 510 (one subtracted is the network number and the other is the broadcast address).

If the static IP address of the router is not in the same network segment as the gateway, an error is displayed. It needs to be set up correctly.

Subnet mask, also known as network mask, address mask, and subnet mask, is a bit mask used to indicate which bits of an IP address identify the subnet where the host is located, and which bits identify the host. The subnet mask cannot exist on its own, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: the network address and the host address.

If the router dials up the Internet, there is no need to set up a gateway.

Computer enters the router]:

1. The computer IP and DNS settings are automatically obtained.

2. Open the browser, enter the general router address in the address bar is this or check the login information on the back of the router) Enter the route - enter the user name and password, (the default is generally admin).

Set Router Dialing]:

1. In the [Setup Wizard], select [PPPoE Dialing] (some are ADSL dialing), enter the username and password (provided by the network service provider) according to the prompts, and save.

2. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPPoe Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

Subnet mask.

You can restore the factory settings of the router, in the reset settings, use the PPPOE method, press the installation wizard, select the dialing protocol and enter the username and password, fill in the correct name, it doesn't matter, about a few minutes or so.

Manually set the IP, the router manual should have it. If the IP address of the router is on the router, the subnet mask should be set to the last one"x"It doesn't matter what the number is, 0 is fine.

All 0 is an unknown network.

WAN port IP, unless it is a static IP, generally does not need you to enter. It can be obtained using PPPoE or dynamics.

A subnet mask is a 32-bit address that is a technique used in conjunction with an IP address. It has two main functions, one is used to mask part of the IP address to distinguish between network identity and host identity, and to indicate whether the IP address is on a local area network or a remote network. Second, it is used to divide a large IP network into several small sub-networks.

Default gateway means that in a home or small office environment, devices connected from the LAN to the Internet, such as DSL routers or wired routers, act as default gateways for other network devices. In an enterprise system, there may be many internal network segments.

A device that wishes to communicate with an Internet address sends packets** to the default gateway of its network segment. Before it leaves the enterprise network, packets may be sent to a series of default gateways that are further away. In this case, each gateway node can also act as a server and firewall.

The subnet mask is used to divide the subnet, with the IP address and the subnet mask, you can get the network number, a network number represents a subnet, the default gateway is the exit of a local area network, for example, the address of the host of an Internet café is generally the default gateway.

1. The subnet mask is used to identify how many bits in the 32-bit binary system in the IP belong to the network address, and the other function is to divide the subnet.

Second, the default gateway is generally the IP address of the network exit, that is to say, the computer in the network goes out through that machine. Generally, the gateway is set to the IP address of the router or modem.
