How does router know which private IP?

How does router know which private IP?

With PAT, multiple addresses can be mapped to one private IP. When a device initiates a TCP/IP session, it generates a TCP or UDP source port number to uniquely identify the session. When the router receives this packet it uses that source port number to uniquely identify the translation.

How do routers identify computers?

Routers identify devices by their physical address, known as the MAC address (media access control address), which is unique. Based on the MAC address, the DHCP service assigns each device to an IP address, based on the list of free and taken IP addresses range it has.

Is IP address specific to computer or router?

That IP address is generally assigned to the router by your internet service provider (ISP); the router, in turn, handles all the traffic from your computer out to the internet.

Do all computers connected to a router have the same IP address?

How does a router know where traffic is?

When a router receives a packet, the router checks its routing table to determine if the destination address is for a system on one of it’s attached networks or if the message must be forwarded through another router. It then sends the message to the next system in the path to the destination.

Does the router determine the IP address?

Routers are special because they have two IP addresses. An IP address is assigned to each of the router’s two “interfaces”. This is the side of the router that faces the Internet and has a public IP address. The second router interface is called the LAN (Local Area Network) interface.

What are the 2 sides of a router?

You can think of your router as having two “sides”: one side is connected to the internet, and another to all of your computers and other devices. The router sits in-between, passing data traffic back and forth. The internet side is a connection provided by your ISP.

Does your IP address change when you connect to different WIFI?

When you connect multiple devices on a Wi-Fi network, each has its own local IP address, which differs from the public IP address. Using Wi-Fi does not directly alter a network’s public IP, but you can use Wi-Fi to connect with a different IP address.

Do Different computers have different IP addresses?

No. Most personal computers are configured to ask the WiFi router to assign them an IP address upon joining the network (using DHCP). Most good routers will assign a unique IP address to each machine (particularly each network interface) a different IP address.
