Do IP addresses vary depending on your internet connection?

Question

For example: will my ip address be different if I am connecting to the internet from a public location such as starbucks or a university campus than from when I am connecting from my home router? Also do computers have individual ip addresses or are ip's determined completely by internet connection? Thanks a million!

Answer 1

It's not clear which of two possible things you mean by "IP address". You could mean the IP address as seen by your computer -- the one assigned to it. But you could also mean the publicly visible IP address, the one others see you connecting from.



The assigned IP address may be the same by pure coincidence. For example, many routers use 192.168.0.2 through 192.168.0.254 as the range they assign to clients. So there's always a chance you'll get the same IP address on two different networks.



However, those are internal, private IP addresses. When you connect out from most small networks, they use something called 'NAT' (Network Address Translation) to make your connections appear to the outside world to come from the router you're connected to. The router at Starbucks is not going to have the same public IP address at the router at your university (or data would have no way to tell which of those two places to go).



Computers have individual IP addresses, but they are typically assigned to them by the particular network they connect to.



You'll get a much simpler answer if you ask a more exact question. For example, when you say "will my ip address be different", it's not clear whether you mean your IP address as seen by your computer or as seen by the sites you connect to.

Answer 2

Yes the IP address are dynamically created each time your connect to a different network and yes computers have unique individual IP addresses in a network.

If the IP address on your home network is 192.168.1.12, it might be different at your university.

However, your MAC address (the physical address) of your ethernet cards remains the same and you cant change it (well, there are few hacking tips to do that)

About your Router, a static IP is always stuck to your router which is assigned by your ISP (Static IP is only for Broadband Connections). It could be Class A or Class B address.

Answer 3

Yeah.



Your IP address is assigned to you by your ISP. Every customer has a unique IP address.



The only time that two computers will ever have the same *external* IP address (this is the only address that matters when you are actually on the *Internet*; when on a LAN, internal IP does matter) is if they are on the same LAN, sharing a single Internet link (for example, two computers sharing a residential Internet connection using a router).

Answer 4

To change or specify the IP address of your computer for your own local area network (LAN), follow the below steps. Keep in mind that if you're connecting to the Internet with a broadband connection, adjusting your network settings may cause issues with your broadband connection. Finally, if your home network is setup through a network router, that router could be assigning your computer dynamic IP addresses, and specifying a static IP address may cause issues. Get to the Microsoft Windows desktop. Right-click on My Network Places or Network Neighborhood and click Properties. Right-click on Local Area Connection and click Properties. Click Internet Protocol (TCP/IP) and click Properties. If this is not present, you'll need to install this protocol. In the Internet Protocol (TCP/IP) Properties window, select "Use the following IP address" if not already selected and specify the new IP address you wish to use. While entering this data, you'll also need to specify the subnet mask and default gateway.

Answer 5

Yes...well, in a way...it's depending on what computer you are using. Your IP address from your home router will always be the same, Starbucks the same, etc. But, the IP at home is different than the one at Starbucks. Make sense?

Answer 6

The public IP address belongs to the issuing ISP. It will only be allocated from any of their outlets. This will actually point to the connection you use. Your private IP will be issued by the service you connect to, and is unrelated. You, could get the same private address from thousands of services. When you browse, sites see your public address, but also record other identifiers from the machine.

Answer 7

IP Addresses are based solely on the internet connection.



For example:

You connect from home. IP: 123.133.0.1

You connect from Starbucks: 890.876.54.2

Answer 8

yes it varys by your computer that you use liek with mine it has 100 then 101 then 102 etc. at the end of it but theres more then to just that there is like 2 or 3 different type's of your address and yur isp assigns them to you not ever one has same ip
