What exactly does the /c stand for? (ie: 192.168.10.24/c)

With CIDR notation, you're supposed to put the total number of mask bits there instead of "c".

Without knowing exactly how you're masking your network off, I can't give you a definitive answer but my first guess is, they're on the same network. (ie: 192.168.10.24 and 192.168.1.1)

For example, the following network would have both the above IP's in the same subnet:

192.168.0.0/20

Which gives you the following subnet mask: 255.255.240.0

to answer your question we would need to see the results of a ipconfig /all from each pc.

usually reason though is you have a router between the two.

Provide a ipconfig /all from each computer as requested.

Also It sometime doesn't allow me to ping.....so is there anyway so that i want both the PC not to ping in between and shouldn't share data....Also both should be able to access internet. I don't have manageable switch....

There are basically two ways to do this, one requires 3 SOHO routers, the other requires 2 internet connections (and 2 routers).

To be honest, the simplest method would be to have two separate internet connections with a SOHO Router between each and it's own subnet.

The more complex method, using only a single internet connection, requires 3 SOHO Routers setup as follows:

Internet >> Router 1 (LAN Ports) >> Router's 2 & 3 (WAN Ports)

example config:

router1:
LAN IP: 192.168.1.1
SM: 255.255.255.0
DHCP Enabled = No

router2:
WAN IP: 192.168.1.2
SM: 255.255.255.0

LAN IP 192.168.2.1
SM: 255.255.255.0
DHCP Enabled = Yes

router3:
WAN IP: 192.168.1.3
SM: 255.255.255.0

LAN IP: 192.168.3.1
SM: 255.255.255.0
DHCP Enabled = Yes

Router's 2 and 3 would have static routes from their LAN side to their WAN side which would give them internet access. As long as no routes between the LAN side of router 2 and 3 are ever configured, they won't be able to communicate with each other.

CurtR he doesn't have ANY routers.

vajay you don't know how to do a ipconfig /all? I have requested this twice from you.
Here is how you do it
http://digitalmediaphile.wordpress....

Since it is clear you have no routers yet want internet on two machines, have you investigated ICS [internet connection sharing]? One pc has to have two nics to do this.

BTW the correct phrase to use would have been:
Why i am NOT able to ping in between these PCs????

He has to have at least one router if he has two separate subnets talking to each other. Unless I'm mistaking what he's been saying about being able to ping between 192.168.10.0/24 and 192.168.1.0/24

"both should be able to access internet. I don't have manageable switch...."
"i have 192.168.10.24/24 and 192.168.1.2/24 "
"both are having gateway as 192.168.10.254 and 192.168.1.254 "

If he had a router why would he be assigning ip addresses? He wouldn't need to.

Best clue is his previous post

Ahhh, I didn't see that post.

The real issue is, not having English as a first language. I had a tough time trying to figure out what his issue was...........it sounded to me like the two networks were communicating.

What is sad is how he ordered two lines but no one said anything to him about putting routers in place so he could nat the two networks.

It is either buy a dual wan port router or two routers and do some manual lan networking.

ip address - 192.168.10.1 ip address - 192.168.1.1

subnet - 255.255.255.0 subnet - 255.255.255.0

gateway - 192.168.10.254 gateway - 192.168.1.254

but ya both have the same DNS....

vijay you are not understanding ip addressing. Having the same dns server means nothing in regard to having two different subnets.

When are you buying a router or routers so you can use these connections?

hi, wanderer i think u guys need word to word explanation....being an expert u should understand the problem immediately....Curt R is also behaving like a beginner.....

my simple question is 192.168.10.0 and 192.168.1.0 both having subnet mask of 255.255.255.0.....are pinging. In general they should not ping becoz of being different subnet ....think big like an escalated issue....

i have tried out on packet tracer with a router and two COMPUTER with different subnet and they dont ping with each other unless and untill i use some routing protocol.....CLEAR U ALL GUYS?????????????

"behaving like a beginner"

"In general they should ping becoz of being different subnet mask...."

Vijay in your first quote above you are being rude. Don't do that. That is not acceptable behavior in these forums.

In your second quote you are wrong on a number of things. First both subnet ranges have the same subnet mask. Second is they should not ping between them without a router because they are two different subnets.

Now if you had used a subnet mask of 255.0.0. then both would be within the subnet and could ping between them if there is a physical route between them.

Please spend some time review ip addressing.

i am not rude ...u r in hurry for replying .....first please understand the problem.....

that was an typos error.....in general they should not ping at all.....think in this way....

one router with a lease(internet) line and two Ethernet ports for two computers of different subnet i.e. 192.168.10.24 and 192.168.1.1 both with 255.255.255.0.....and no 255.0.0.0

so they must not ping but they are pinging....y? without advertisement ie routing protocol like rip v2 etc....

Because you have same subnet mask and both the computers are from the same network i.e class C and are coming from the same router so the they are pinging.
