Every time i go to whatismyip from different computers it always shows the same IP. I have a dlink router. Every computer has has a different local IP but the internet IP always stays the same. I have changed it a couple times by changing my router MAC address but it always only gives me 1 ip for all computer. Is this normal? I thought every computer has to have a different IP? Any comments are welcome. Thanks!
This is perfectly normal. Each computer on its own network must have its own IP. So your network of computers do have their own IPs.....192.168.x.x. There are finite amounts of public IP addresses. For home users, 1 IP is plenty, for small businesses, 1 IP is plenty as well.
If you're interested you can Google IPv4 as well as IPv6. This will explain the amount of IPs available on the internet.
