I am wondering how I am able to change my IP address from Japan to Canada?
Any help is appreciated.
You'll have to find a proxy server found in the country you're looking for. Why are you wanting to do this? You know that no matter what you do, people can locate you, even if you use proxy.
i hope you know that MAC ID's are universal identifiers. you arent allowed to change them. they are like your credit card number, they only exist once. i wouldnt go messing around with that, unless its legal..
I think you are confusing a IP address with a MAC address. An IP address is a set of numbers (only) that are determined by your "location" on the internet from your ISP. and the ISP can change it as often as they like (and apparently they do). However your MAC (Media Access Control, i think) is hardwired into the hardware, and it would not surprise me if it was illegal most of the time.
no lol i wasnt getting confused.. i just didnt fully understand what was going on. and still dont...
wat is the OP wanting to change?? so confused, sorry. its been a long day
Why would it be illegal to change MAC address? It's used to address the hardware on the local LAN. Mac OS X allows you to change it with ifconfig lladdr in terminal. I think it was possible to change in system preferences before.
It is some times necessary to change MAC address when two interfaces get the same number. And yes its possible, I had it happen to me.
how is that even possible?!?!?! the MAC address is supposed to be a unique identifier. that silly if there are conflicts then, unless they were the same products, which would then make sense.
Yes, they were same products, had the same company prefix. But companies reuse them when they finished the serie. Usually they dont sell products with same mac addresses in the same country, or area and so on.
The products were bought some time appart, dont know exactly how much time appart.

btw, I think the meant Mac, not MAC =)
that would explain it then. i thought that generally changing mac addresses would be illegal. with mac addresses its easier to get onto different networks (i.e. hacz0r1ng). thats illegal isnt it haha
that would make it easier to understand then
Yes, but I dont think anyone serious with security would rely on MAC addresses, MAC spoofing isnt anything new. It's used sometimes in addition to security on WLAN's, or to identity workstations, or catalog hardware for instance at schools.
An example of MAC spoofing that was or maybe still is popular is when you want to sniff switched networks, or redirect traffic, or simply DoS. You send out spoofed arp reply packets with your MAC address and the gateway/router ip address, that way the arp tables on all hosts will be poisoned with your mac address for the gateway ip and send all their traffic to you =)
I remember we had to set router address as a permanent entry in the arp table on servers so that they werent taken offline by script kiddies who forgot to route the traffic to the real router =).

thanks for the info. ive always been interested in checking out the vulnerabilities in wireless networks. there are quite a lot. im oging to major in security in Uni when i go next year. always been interested in it. maybe its cauz i like helping people and pointing out their flaws
