LAN IP Expansion 100

There are several methods, it is too long to say, just simply, use the routing method: 1 is to draw val, this method is the most feasible to share the submask, you can increase n machines, and there is the ip** function of setting different network segments on the route, that is, the same public IP, with multiple intranet IP addresses. I don't know what kind of route yours is, H3C has these features!

The method is too simple.,It's okay to connect a router.,Treat this router as a secondary router.,The secondary router doesn't use your current network segment.,Isn't it expanding the IP.。

Shared Internet access. Generally, either ** or nat is used. Internet café now.

It's all with NAT. Multiple computers share the same IP. But.

Net-in-net. I haven't done it... If possible.

Get a router. Make a subnet out. Of course, the router has to be configured.

Just search for it on the Internet. But I don't know if it's possible. If possible, remember to send me a message.

I want to learn too ...

You can let you have an arbitrary public IP address, connect to a router, and the router can have the function of going to different network segments, that is to say, you can specify n machines arbitrarily on the intranet, but use a common IP address externally.

You are using a Class A private IP address, which supports (2 to the 24th power minus 2) hosts. Now your problem can be solved by modifying the subnet mask, you can change the subnet mask to , so that you can have more than 1000 hosts in your local area network. The available IP address ranges are:

You've got 500 IP address ranges. From to, there are at least 252 available IPs, and then to another 252 available IP ranges. The subnet mask is recommended to be.

What else do you want to expand?

A few more Level 2 routes are sufficient. You can do as much as you want.

There is no cost.

But I don't agree with the point of view upstairs.

I don't know what the size of your company is, but in the long run, you really can't add an address at will, and the address needs to be carefully planned. As for the problem of conflicts, it is the lack of maintenance by the actual operators. If the address of each machine is fixed, how many devices and how many addresses are needed in the whole company can be controlled, and there will be no conflict.

It doesn't cost to increase the address, so why can't you increase it at will?

This is to match the development of the company, for example, you are now using two addresses, 100 and 101. When a company establishes a branch, what address should the branch use? Do you use 100 and 101 too?

It's easy, but it's wrong. What if one day, the company is developing very well and needs to integrate the network resources of the two branches? You'll find that all the addresses are conflicting, the configuration of all the network devices is also conflicting, and the entire network has to be rebuilt.

While most companies do or never use this situation, this kind of planning is certainly not responsible. Therefore, for a company with "goals and ideals", the use of addresses must be precise for each one. You can't add addresses as soon as there is a conflict, you must first strengthen the management of addresses, otherwise as soon as this IT leaves, no one can understand the entire company's network.

1 No cost, don't buy hardware, re-plan the IP segment is no problem for you to allocate, and there will be no conflict.

2 The new problem is that after you solve the IP conflict, you can't remember which machine uses which IP in the future network management.

All machines are on the same subnet, there are too many network broadcast packets, what should I do if there are so many machines in the network storm, the network egress, is the bandwidth enough?

This is still a network planning problem, and the basic problem is not clear.

No cost, the LAN setting is unreasonable, and your company's network configuration personnel do not consider the long-term.

Your design is very good, but you can set a DHCP address pool, and the mask is uniform, and the default gateway and the reserved IP address are unchanged.

If you adjust the subnet mask of the LAN, then the address of the entire client LAN has to be changed, instead of borrowing only one bit, it is better to use the subnet mask of 16 directly, and it is easy to calculate.

How to set the IP address of the computer network.

254 addresses not enough? You run an Internet café? It is recommended to use a switch and a soft route.

1. Under normal circumstances, these can be used as the default LAN IP address, and I estimate that no company in the world dares to say that the LAN IP is not enough.

2. The PC machine is connected to the switch, under normal circumstances, the PC is originally connected to the switch, and only the home user is directly connected to the router with a computer.

3. The local IP is the WAN IP, which should be the computer directly connected to the external network cable. In this case, if other computers want to be in the morning, you can only use your computer as a dual network card**. If you say don't **, don't route.

Then the other computers can only stare dryly.

4. If you want to increase the IP address in the above situation, you can only find a local operator to give you a few more external network IPs.

After all, there are more than 250 intranet IPs, if it is really not enough, you can use the network segment that is rebuilt by the router. This method is suitable for homes, small businesses.

What you're running into is an IP allocation planning problem.

If it is convenient, please tell me how many computers do you have in your company now, and you need to connect to the local area network?

If there are no more than 250 units, then there is no reason why your IP here is not enough.

If it is exceeded, you can enlarge your subnet mask on it.

The LAN uses a private IP, you can't change it, this problem should be that the IP range of the switch you use is limited, it is recommended to negotiate with the enterprise network management! The IP starting with 172 can accommodate a lot of computers.,To。。。 So much so huh.

How many computers do you have in your local area network? If there are more than 254 IPs, use Class B reserved IPs.

If the number of duplicate IPs is not exceeded, it is generally caused by manually setting the IP, you can enable the DHCP service on the router, and then all computers in the LAN will automatically obtain the IP.

1. If there are no more than 254 devices, you can reduce the lease period of IP addresses in DHCP to better allocate IP addresses;

2. If there are more than 254 devices, you can add IP addresses by dividing network segments.

Set the range of the IP address pool in the DHCP server to a larger extent.

How many IPs do you want? One segment of a Class C network can accommodate 254 machines! If you want to divide 2 network segments into one network segment, you can divide them by subnetting! You can set the IP address to:

Then and both belong to the same network segment, which increases the number of IPs!

For specific subnet division, you can go to find information!

That's what I'm telling you!

In this way, the sum can be interoperable without the need for additional equipment.

Not enough LAN IP? How many computers do you have on your LAN? It's not that it's not enough, it's just that there are two computers with the same IP.

Find out these two machines, and change the automatic IP acquisition of one of them to a different fixed IP.

It's not that it's not enough, it's that someone changed the IP without permission

In the route, the gateway does not change, the mask is changed to the original machine IP address does not move, the gateway does not move, the subnet mask is changed to the extra machine IP address is the gateway subnet mask is changed.

Buy a switch with Layer 3 routing and re-plan the address. Different departments use different address ranges. Such as, etc.

If the subnet mask is set to 255255254 0, there will be 2 segments available, and if you set it to 252 0, you can use 4 segments at the same time, theoretically, if you don't consider the broadcast storm, you can set it to 255 0 0 0, and there will be 255*255*255 available addresses. Actually quite simple things

Just open a new network segment and use a router. Preferably Cisco's, 3com's will do. It's easy to manage, as long as you invest, hehe, everything is not a problem.

It's not as complicated as the 1st floor says. All you have to do is change it in your router and you'll have 745 more IP addresses than you would have before.

This is simple, add a new network segment, you know within the *!

Steps: Add a new router! Assign an IP address to the new router under static IP binding, and then if you want to save trouble, you can enable DHCP, if you don't want to save trouble, you can set the IP address yourself!

Remember that the gateway of the router must be changed! Generally, the default is OR , and the gateway you add should be remembered!

You can use a class B address, but there will be a lot of problems with too many computers in the same network segment, it is recommended to divide it with a layer 3 switch, or invest less, like Hua 3 enterprise router four ports can be divided into 4 address segments, 4x254 is enough for you to use it,

You can use the IP range of different network segments for the department according to the current situation of your company, such as: etc. Then purchase a Layer 3 switch device or a configurable router, and then configure the IP ......gateway of each network segment in the deviceAs for the configuration method, you can ask the supplier and equipment manufacturer technical support!

You can use thank you to interconnect.

Expand the address from.

The configuration method can be found online, or I can provide it to you.

With the expansion of the scale of enterprises and institutions, you will encounter more in the future, it is better to expand the network equipment now, and plan first.

Multiple network segments.

Then connect through the gateway as a router.

At present, the easiest way is to redivide the network segment and add switches, so that the theoretical 255 can be met without major actions

Divide into 0 and 1 sections by office or floor. Let's use the method of an Internet café. Convenient shortcuts for now.

You can use the router cascade way:

1. Modify the third group of IP addresses of the secondary router to not conflict with other routers;

2. Connect the LAN port of the primary router to the WAN port of the secondary router;

This can be set to the primary router and the secondary router, which can effectively increase the intranet IP.

Can I add routers and switches to achieve this?

Isn't it possible to add the CIDR block if you change the subnet mask?

Then you use the add, subnet mask as, for example.

We can provide you with an approximate network topology diagram of your company, as well as the model and function of the network equipment.

Detailed needs to design your company network according to your specific needs.

Generally, we use the following three private IP ranges:

Class A: Class B:

Category C: Also, a few small suggestions. DHCP is recommended if there are no special requirements.

This can greatly reduce your workload. In addition, you can divide the network segment and plan your company network. It is usually divided by department.

Just buy a junction box.

One IP for multiple computers

I have 3 computers with one IP right now

Directly on class A, such as similar, it is difficult to think of super.

You can add an address range.

Adding a switch or wireless router may solve the Internet problem.

Your address can only support 254 computers. If the superior assigns you that you can't change the gateway configuration, then you can't expand the capacity.

Feiqiu (feiq) is a green software for LAN chat transmission files, it refers to the flying pigeon (IPMSG) and QQ, fully compatible with the flying pigeon (IPMSG) protocol, with the advantages of LAN transmission, fast speed, simple operation, and at the same time has some functions in QQ, is a perfect alternative to the flying pigeon.

Hush. Secretly go to the friend you want to add and install this software.

Most people don't use it, no idea.
