IP addresses?

Question

when different devices are connected to the same wifi modem would they all share the same IP address space or is it unique
and when the device is later connected to a different modem would the IP of the device change?

Answer 1

On the LAN (your local area network) all devices have a different ip address, your router which connects to your service provider is given a specific ip address by their server. regardless of the device connected to the LAN the external ip is the same. Connecting to a differnt modem would change all that, however, the ip address is not the only thing that is vuisible in either case, every device that can connect to the netwiork has a unique identifying number called a mac address which never changes.

Answer 6

They all Share the same PUBLIC IP Address... or WAN IP of the Modem.



Each connected devices will have a Private IP Address which changes in the order the connect to the network... 1st comes 1st serves.

Answer 7

When a computer is to connect to a network, the computer has to have an address on the same sub-net as other devices that it is to work with. The address on the sub-net may either be configured manually, or the addresses may be assigned automatically to each device by a server, that can be integrated into your router or might be special computer that carries out extra validation that checks that the access to the network is valid. All devices on a particular network have to have their own unique address on that network.



Home routers include a mechanism called NAT (Network Address Translation). This mechanism allows multiple computers on the private network to share a single IP address on the Internet. This address follows the same rule, and is unique on its sub-net - the Internet.



For home routers, the address allocation is performed by a DHCP server, which is a small routing running in the router. Addresses are allocated for a fixed period of time (often around 24 hours). If a computer is still connected to the sub-net when some of the time has elapsed, then the computer will ask the DHCP server to renew its address. It will keep the same address, but the end time will be extended. If the computer is no longer on the sub-net, then the address will be freed for other devices to use when the time expires.



If the computer rejoins the network before the time expires, the router will allocate the same address. If the time has expired then the computer may be given a different addresses.



I hope this helps.

Answer 9

When wireless devices connect to any router that they have access to, they will receive a dynamically set Internet Protocol Address, this address cannot be used by anyone else until they log off of the network or leave the range of the routers wireless signal. Unless specified other wise in your Advanced Wireless Access List directly on your router, your Internet Protocol Addresses will change each time your log on to the wireless network. Private home networks usually use the Internet Protocol Address ranges 192.168.1.2 - 192.168.1.254, unless the admin of the router has limited the scope range of allowable IP addresses those will be your choices. There are three reserved IP addresses on this network, 192.168.1.0 unusable, Your routers IP 192.168.1.1 and your broadcast IP for that network 192.168.1.255. I hope this has helped, and yes the IP's will change when you connect to different networks, it is does this dynamically(Automatic) using DHCP and DNS. I will not explain DHCP and DNS here because we are getting a bit deeper into the technical terms and rules that may just bore you to death. My suggestion if you are interested in learning about DHCP and DNS, google is a great tool.

Answer 10

all devices have a different ip address, your router which connects to your service provider is given a specific ip address by their server. regardless of the device connected to the LAN the external ip is the same.

Answer 11

I believe each machine has its own individual ip address known only to the router, while the router has its own external ip address for connecting to the internet.



The internal ip addresses are temporary so yes, will change when hitched to a different router - probably even the same one if it or they are switched off and on again.

Answer 12

IP address is depend up to internet device connection.

Answer 13

IP addresses for devices connected by router are same, but their mac address is different for all devices connected devices.

Answer 14

IP address is given by router.If you move device to different router IP address will change.

Answer 15

If your modem has more than one LAN connector then it is also a router. It is common to combine a modem and router into one box, but you may have a modem connected to a separate router. The router uses DHCP to allocate local IP addresses to the computers, printers etc on your local network. Whenever one of them connects outside, ie on the internet, the router acts as a proxy using it's internet IP address. This is called a firewall, so that hackers can not see your computers.

Answer 16

IP address is depend up to internet device connection.

Answer 17

ip address is like telephone numbers & are unique....If u are in one private network which is using wifi modem then all devices connected to that private network have different ip address & if two devices have same ip address then they don't get the network & obviously no internet as well...In that case u need to renew your ip address in order to get new one..

Now if you go to another network then you'll get another different ip address for your same device...So in each network you have different ip address...Just try it yourself....

Answer 18

Think of it like a telephone system.

You have a phone number assigned which receives all calls coming in and going out.

Within the business each phone has an extension with it's own unique internal number.

The internet works the same way with the external IP assigned to it by the ISP. Your internal extension numbers are all controlled by your network personnel.

Answer 19

there are 2 IP addresses - the local one and the WEB one



the web one is the IP address your ISP normally allocates to your router ,



the LAN one is the IP address your router allocates to the devices connected to it

Each device (including wreless) has its own unique local IP address



Move the device to another router it will get another local IP address.



All traffic from all devices to the internet is routed via the router and that 1 WEB address ,



The router ensures traffic from the WEB is routed to the correct local IP address

Answer 20

IP address is unique for each and every system..that uniquely identifies it from all other computers on the Internet.

Answer 21

so when your device connects to a modem, it assigns it a port. when data is sent to that device it is sent to [modems unique name]:[port of device]. in this way, every ip in your house will start the same and have a different port number.
