Why does my router have three IP addresses?
This would indicate that the PC has connected (been rebooted?) 3 times and each time the router has assigned a different address even though it still has the previous addresses in its table. A router should normally reassign the same address so this may indicate a problem with the router.
Does my neighbor have the same IP address as me?
When you use the Internet, your internal IP address is hidden and only your external IP address is seen by other computers on the Internet. Therefore, all devices connected to the router (whether wired or wirelessly) will share the same external IP address.
Can two routers generally have the same IP address?
No two routers cannot have the same ip address. If the ip address of a router overlaps with another there will be an ip conflict detected by the routers and the same is informed by log messages.
How does the IP address of a router change?
Your router is connected directly to the Internet, and it’s assigned your public IP address (which may change over time). Your router is then responsible for sharing your public IP address among the other computers and connected devices in your home. Your router assigns local IP addresses to your connected devices.
Therefore, all devices connected to your residential modem/router on your LAN will share the same external/public/WAN IP address. However, each connected device will have a different internal Internet Protocol address as assigned by the modem/router/DHCP Server.
Are there different IP addresses for different devices?
The Answer. All devices on the network are given a different x value (1-255), the last digit. Here is an important distinction. There are 2 types of IPv4 IP addresses, Public and Private. Public IP addresses are the ones you see on the Internet (if you ping google.com you will get a public IP address).
