Hi All
I am confuse on IP address. I have laptop and its connected to internet and now I am accessing website of AAC. I think when My laptop connect to internet, ISP provide IP address to my Laptop like 198.167.x.x Will it change every time? Will ISP provide new address every time? after reading about it on internet. I think yes ISP provide new address every time.

There are three people in my room. We all have laptops and one WiFi router. We all access internet via WiFi router. In this case what happen Does ISP give IP address to all laptop's I think yes. Does it give IP address to WiFi router ? I think Yes, Will it change every time ?

Do people know only the address of the router or they will also know the IP address of the laptop's ?

 

The laptop is assigned an IP address by the wireless access point when the connection is established. This is handled by the DHCP client of the access point and it will assign the laptop an address within it's DHCP range which has not been taken.

The subject of how an external server communicates with host inside your home network is little more complicated. This very similar question on stack exchange may help you https://superuser.com/questions/105838/how-does-router-know-where-to-forward-packet
