    How are IP addresses assigned?

    Are IP addresses assigned by electronic devices being used, or by the internet connection?  For example, if you visit a coffeehouse with WiFi, is everyone online at the same moment there recognized at the same IP address, or are they identified by their unique device?

    The WiFi provider/router will assign "local' IP addresses to all computers connected to it.  These are special addresses that internal networks use that do not contact the external internet. See http://en.wikipedia.org/wiki/Private_network  The "external" IP will be the same for all, and you can see that by visiting a site like http://whatismyip.com  The router forwards all external communications to the proper internal client.  If a connected computer wants to run a server program accessible from the outside world, the router must be configured specially to forward a "port" from the outside to the appropriate internal IP.

    they are identified by unique devices.

    the coffee house uses a router. the router dishes out the IP addresses to all the computers/phones connecting to the internet so it can identify who clicked a certain link and show the right person the right results ... (not your neighbor) [similar to waiting tables i guess ... each table has a table number so the orders don't get mixed up]

    the router also has an IP address assigned by internet service providers (ISP). there are classes of IP addresses depending on the size of the network. for example an ip address that starts with 192 or greater is a class C network and can only contain 254 computers...

    When you disconnect your computer from the coffee house network and reconnect you can be assigned a different IP address by the router ... although your "MAC" address which is a hardware address of your wifi/ethernet port device will remain the same and cannot be changed ... (some software are available which do allow changing of your mac address). there are standards which manufacturers have to follow while naming hardware devices...

      I agree with you...i have cross checked this.I and my friend went to the nearby coffee shop and once we got connected to the internet...we visited http://www.ip-details.com/ and we got different IP addresses.

    192.168.1.1 stands out as the default IP for some home broadband internet modems. It has been initially utilised by Linksys although has been discovered used in various other home network products just like the ones made by Netgear as well as Westell for example.



    Despite the fact that 192.168.1.1 stands out as the default ip for numerous high speed broadband wireless routers, this does not always need to be. A large number of producers set the default IP to 192.168.1.1 so that they can publicize a far more standardised processing natural environment and to make it simpler for newbie end users to setup their own network systems easily.



    Can just Linksys together with other wireless routers work with the 192.168.1.1 IP address?



    Basically no, due to the fact 192.168.1.1 is definitely a non-public IPv4 address, any kind of computer system, wireless router, device, or another web-based system could be set up to employ that IP. Nevertheless, it's not in most cases suggested because there are lots of products which default to 192.168.1.1 of which connections troubles might develop soon after from many different products utilizing the same IP. It's also significant to keep in mind that one network machine can get just one single Ip, if you have got numerous products using 192.168.1.1, just about one of these will have to be modified to a new location.
