Ok can anyone answer this

Say if you have NTL cable broadband and you have a router so you are running 3 PC's in your house through the same internet connection.

If all 3 PCs set up a different hotmail account and send mails to me will all 3 emails have a different IP address or will the IP be the same as they are from the same ISP account.

I know the router assigns each pc in your home with its own IP address but i thought that would be kept internaly on your network

 

I know someone with this setup and think i have recieved some hoax mails from one of their kids, only the last 2 digits of the IP is different from their parents e mail so thats what makes me think the mails are coming from the same house.

 

Anyone any idea??

all internet traffic should follow the router connection's IP. If you go on any computer in your network and go on this site http://www.whatismyip.com/ you'll get the same IP address which is the hook up addy to your ISPs servers.

 

the IP addys that the router gives out is only for your internal network. the outside world wouldn't see it.

only way to get diferent IPs is to install an IP generator on every machine.

If the router doesen't have built-in NAT, the IP's of each machine will be different. If it has NAT the IP of each machine will be the same outwards, but they have their own IPs for your local area network.

The router will use NAT and also DHCP to allocate your IP dynamocally but as for what people outside will see,they will see your WAN IP.

 

Your local IP's will usually start with 192.168...
