I have a dynamic IP address setup for my MacBook. I need to develop a completely new IP address (one that has not been previously used on my laptop). If I use a different network (i.e. log onto someone else's Wi-Fi network in which I have envier been connected to), will that guarantee that my IP address is different from any IP address I have ever had before, given that it would be my first time logged on to that network?
Also, I'm not all too familiar with tech talk so please excuse me if my question isn't all too clear.
You have a public IP address that identifies your connection on the Internet. If you have a NAT router, you will have a private network with private IP addresses that do not reach the Internet and are mapped to the public address by the router.
The private addresses by default are assigned by the router from a pool of addresses that have been configured in the router. Alternatively, you can give a specific device a fixed private address providing it is within the subnet the router is using for its private network. If you set up a direct connection between two computers without a router, you have to give each computer a fixed (static) address.
The public address is assigned by the ISP to the consumer connection. Unless the ISP assigns a fixed (static) address, it may change to a different address from time to time. The ISP will have a block of addresses allocated by the Internet authorities from which they can assign the addresses to their customers. You have no choice but to use the address assigned to your connection.
If you go to a different ISP, then you will have a different public address. If you go to another home with the same ISP, then you might get a public IP address that was assigned to your home previously.
For private addresses, then these are duplicated in millions of households around the world. Since they are not allowed on the Internet the same addresses can be used by thousands of people. If you set a fixed static private address on your Mac, it will not work if you connect to a different private network that is using a different subnet.
I hope this helps.
I can't imagine what you are trying to accomplish. If you are trying to change your local ip you can just do that through Network settings in System preferences. If you are trying to change your public ip, just unplug your modem for a few hours or over night (Your ISP gives away your current IP when it sees nothing on it for so long).
Again, I think you need to explain why you want to do this so we can give you better advise on how to do what you need. I can't think of any reason someone would want to change their IP who doesn't already know how to.
You do not have an IP address. You borrow an IP address when you connect to a network. Your ISP allocates an IP address to your connection at your home. If you visit someone else and use their connection you will be using the IP address allocated to their connection. When you return home you will be using the IP address allocated to your home connection again.
Your IP address is assigned by the ISP….not by a wifi router…..the router address assigned to devices will vary from one wifi unit to the other and by how many devices are logged in…..But your home IP address comes from your ISP….
Example… my ISP assigned the address……255.255.268.127 to me…..now my router has 3 devices connected to it….the TV is 10.0.0.1….the computer is 10.0.0.2….my phone is 10.0.0.3
Now I stop over a friends house….there home IP address will completely different then mine….
Back up and tell us why you think you need a static IP. That may affect the answers you get.
No. If might give you the same up address.
