Is subnetting only be able to configure via router and not individual computer?

Hi everyone,


Is subnetting only be able to configure via router and not individual computer?
Is any ISP router support subnetting, where can I find it for the router configuration?

Regard.

Routing is normally performed by a router, (the clue's in the name), you can use a PC as a router and even run multiple subnets, but you will need at least one Network Interface for each Subnet, plus specialist software or a full knowledge of the command line command structure for networking.

I've not seen any home user router that can perform proper sub-neting, which you normally control using a managed switch, the word router is normally reserved for devices in the home or those supporting Wireless.

First place to look would probably be someone like Cisco they have a library of information, a lot of which is available as PDF

The router has to be programmed to allow subnetting plus have multiple independent interfaces. Home routers don't usually have that and I actually don't know of any that do since most homes don't do this. You will have to get an enterprise sized router from for example cisco. Perhaps this should be merged with his previous thread. http://www.vistax64.com/network-sha...ress-different-subnet-still-has-internet.html

Hi barman58,
Example: So let say that I want to use my laptop for subnetting by default it has 2 network interfaces installed like any laptops. Example: ICS connection: Depends which network interface card another LAN network computer is connected to your computer it only get the IP Address of that specific IP Address range, is that right?

Suppose subnetting can get any subnet IP Addresses of any numbers of subnets that you configured, is that right?

As my 2nd thought configuring a pc for subnetting as limitation on it because of the slots available on pc, is that right? So when is the right moment to use a pc for subnetting? It's for 2 subnet configuration only?

Can you give some samples of command line command for subnetting configuration please.

Sample of my own experiment on my laptop:
My LAN IP Address: 192.168.0.170
Subnet Mask: 255.255.255.0
Router IP Address: 192.168.0.1

Subnetting configuration:
My LAN IP Address: 192.168.0.129
Subnet Mask: 255.255.255.128
Router IP Address: 192.168.0.1

Error message:
The default gateway is not on the same network segment ( subnet ) that is defined by the IP Address and subnet mask.

How to configuration router IP Address and have internet the same time?



Regard.

Hi townsbg,

Do you mean router configuration, may be DHCP configuration section most likely?

Myself as well as at least one other person have stated multiple times on your 2 threads that home routers are not set up for subnetting and that you will need a router designed for businesses to do so. It doesn't matter what it is missing just accept that home routers aren't designed for subnetting because homes have no need for it. Now if you need to subnet buy a business router but if all you want to do is learn it just look for documentation or find an online course. However these discussions are beyond what we do here.
