This question is very vague. I'll try to answer it in a variety of ways. If you tried to take another computer's IP address you would have a conflict and both machines would not be able to access the internet. If you are trying to acess any netowrk without the network provider's consent then that would be considered illegal. Companies would have policies that would not allow you to perform any network configuration and if you violate that policy you are subject to their punishment.
Yes.
Mac address.
The ip address is used when another computer needs to connect to your computer or if you are hosting a site on your server. The ip address of your site will be the ip address of your computer. The IP address is used when communicating with another LAN (Local Area Network) across a WAN (Wide Area Network).
IP spoofing is the process by which an IP address is created in order to conceal the senders identity or impersonate another person's IP address. IP spoofing is a crime and punishable by law.
As long as you are not performing illegal activities, then it is perfectly legal to hide your IP address. There are lots of benefits from hiding your IP some of them include:Sites can't monitor you.Freedom from pop-up ads.Protecting you from spyware.Computer works more efficiently.
An ip grabber is a program that will find the ip address of another computer. Often used by hackers.
There isn't one.
Your public or external ip address will change, but if you use a router and you have things setup to use a static ip address then your computers private or internal ip address will stay the same but your public or external ip address will still change. Public or External IP Addresses are assigned by your internet service provides. Private or Internal IP Addresses are determined by your router if you have one.
It depends on how your computer gets its ip address. If you have a static ip address. The answer is no, your ip address does not change. If you have a DHCP server in your network mostly likely you will get another ip address when you change your computer. There are some tricks but it's a too long story.
Your IP address is th internet connection you have. You can not change your IP unless you get another internet connection.
That doesn't happen. If it does the workstation gives up the IP address and remains unconfigured until the DHCP server grants it another IP address.
Each IP address in the list are the IP addresses for all the servers along the way. As the email is sent from 1 server to another, it's IP address is added to the header. This way, we can trace from where the email originates and it's path to the destination.
