Say a home network is connected to the internet via a router. Two computers are connected to the internet via this router. Their ip addresses are different. How can a site deduce they are from the same network via the ip address.

Can't. You can only tell the ip address of the dsl modem.

you have the ip address and the network mask. if using windows go to the command and type ipconfig /all that should give you all the info that the (dhcp or modem router ) is giving you. The information about the default gateway should be the same on both and the dns settings should also be the same. basically you check all the settings and appart from the ip everything should be the same. another way to know is by checking that the ip's are on the same range. meaning that the subnet mask shows you where the ip has to be the same and where it has to change. for example the 255 section means that the number pertaining to that group should be exactly the same for both. so if you have 255.255.255.0 the first 3 groups shouls be exactly the same and the last one can be different. It is more complicated than this, but this is the general rule.

Yeah. Your IP address is assigned to you by your ISP. Every customer has a unique IP address. The only time that two computers will ever have the same *external* IP address (this is the only address that matters when you are actually on the *Internet*; when on a LAN, internal IP does matter) is if they are on the same LAN, sharing a single Internet link (for example, two computers sharing a residential Internet connection using a router).

The site only sees the router's public IP address. The private IP addresses of the individual computers are NOT available to the site. All computers behind the router appear to be a single computer to the site.

Their internal IP address is different but the Gateway IP address that the internet see is the same. That would be the IP address the modem is assigned.

If their IP addresses are different, they are on different connections to the Internet. You can check their IP addresses at arin.net to see if they are each using the same ISP for whatever good that might do you...

My forum uses this site to help me track my members: http://www.apnic.net/index.html
It's pretty accurate. I think try looking in the Whois database. Then find on each of the computers what their IP addresses are, should be in the Internet connection somewhere. I'm sorry.. I'm bad at explaining things when it comes to computers!

the Ip address has 2 addresses, the network address and the system address. if 2 systems are from same network they will be having thae same network address

It's easy, the extension (the last part) is the only thing different.
say,
192.002.032.011
and
192.002.032.062
they're behind the same router.
(not sure if that address syntax is correct, but i'm at school, on a lockdown computer, so i can't look at mine)
