Dsl Ip Address Sharing-----Testing Number Of Users On Ip

[sailaway2000]

I have been a 3BB Premier user for nearly 4 years at about 1100 baht per month. 3 down 1 up max speeds. And presumably better for international service.

This subscription is no longer available.

I once heard that the maximum number of users on a specific IP was 20 for the Premier service. Is this still true?

Generally speaking the service has been quite stable, without many problems, especially in the past year or so.

How would I, or can I, test the number of concurrent users on my IP address?

Thanks

Nobody else is using your ip address!

What they mean is that the contention ratio is 20 to 1 on your connection, meaning that a 3/1 mbps international connection is shared with maximum 20 other users (each with their own public ip address).

No way that I know of for checking that though, best inication would be how stable the speed stays during a large download, and especially latency to known overseas servers.

Connections with high contention ratio's tend to have high ping times during peak hours as a result of requests getting qeued...

I don't know about 3BB or the network architecture of the ISP but you can do a PING inside the range of your network layer or try to find the ARP package connecting directly to the modem or router in bridge mode, pretty difficult for an average user.

in CMD you can try something like this

FOR /L %i IN (0,1,256) DO PING 192.168.1.%i

replacing the ping 192.168.1. for the ip of your gateway or your segment.

for know that you need to look into your routing table if you are connected directly

NETSTAT /r

or into your router WAN status

Just to add to Monty's response regarding the contention ratio, I think this Link provides a good explanation of how the contention ratio sharing occurs.

yes good explanation, I didn't known that

[sailaway2000]

Thanks for the reply.

For your command line :

FOR /L %i IN (0,1,256) DO PING 192.168.1.%i

What do I replace the 192.198.1. %i with?

You are connected to the router in DHCP mode

thats mean your IP 192.168.1.2 is connected to the gateway 192.168.1.1 (local area)

you need to connect directly to internet I mean something very unsafe if you don't know what you doing.

if you have a modem connect directly to your PC and setup the PPPoE connection the user pass of your ADSL connection

if you have adsl router you need to go into your router and change to "Bridge Mode"

so when you do the netstat -r the first line shoud show the IP that your ISP give you (usually the public IP) and in green the Gateway so you must use the 3 first numbers of the Gateway.

Network Destination Netmask Gateway Interface Metric

0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.2 30

70.42.244.237 255.255.255.255 192.168.1.1 192.168.1.2 1 ....

But this is all theory or a play since the unique thing that you will do with the command line is know how much computers are in your segment,

Monty already explain about your Plan

if you want to play with the command line the most easy thing is take your Public IP and and take the tree first numbers

my IP address is 118.173.166.110

so the command line for my is

FOR /L %i IN (0,1,256) DO PING 118.173.166.%i

BTW have you a VPN?

70.42.244.237 <- this is strange 255.255.255.255 192.168.1.1 192.168.1.2 1
