Default IP encryption

Does anyone know if there's a way to encrypt a windows ip address to look like a mac address?

Hmm what do you mean?
You do understand that the mac address is for network ... so there is a big difference between an ip address and the mac address
If you mean you want to hide your ip then just set up a proxy server with all the correct ports and all that

It is also possible to "spoof" your MAC address, if that helps.

I've never done it, and don't know how, but it is possible, at least so I'm told.

What dyserq said sounds about right. I want to convince a network that my windows xp machine is actually an apple running a mac OS.

Ahh deathagent
I thought that you meant it like as in you want your ip adress to see your mac address
By the way, the mac address is like a ip address except it is designated for a network
To my knowledge, i am not sure if you can ... i'll check up on it though

There is no difference between a Windows IP address and a Mac IP address. A network would not be able to tell the difference between your operating system by IP address alone.

Wireless networks are able to filter windows' ip ranges and only allow macs in. This is what I'm trying to get around since all windows OS computers are filtered for "security reasons," in the *public* network I wish to use.

What do you mean by filter deathagent ?
Now i am pretty sure that you can't because from a single ip you can only find out a few details such as hostname, isp, city location and time zone that they're in
I don't think that your os is included in it

I'm not really sure, but my "theory" is that there are ranges of numbers that are only used for ip adresses of windows OS' and ones that are only used for mac OS', so by encrypting the IP of a Windows machine to that of a Mac range the network could be used, but then again that's just my theory... I could be completely off and just dead wrong.

Hmm i don't think that that is the case though ...
The operating system stil doesn't affect your ip address
The internet protocol is a universal system, they all have to link to each other in uhh ... kind of like the same format or kind
I mean, people use linux but it doesn't affect their ip address at all, your isp doesn't change your ip when you change os so from what i see there is no difference

I guess my queston now turns into: "How do wireless networks filter Windows' OS' and is there anyway to get around it?"

I'm sure the network your describing is using MAC address filtering. You say your trying to connect to a wireless network of some kind, so most likely if this network really only allows certain computers to connect, the network is most likely filtering each machine by MAC address, which BTW is hardware specific not software.

MAC address filtering in wireless networks is actually more common than you would think, and certainly more secure than just encrypting your connection. Basically there is a database of allowed MACs and anything not in the database is not allowed to connect to the network.

I think what deathagent meant was that if there is any difference between a windows os ip address and apple os ip address, although the correct mac term is used to identify a computer on a network
I still don't think that there is a difference between ip addresses ...

So all I have to do is find out the allowed mac address(s) and then change my computer's mac address, as described in the link posted by x0r515t, to gain access to the network?

This doesn't take into account separate wireless cards. For example, if you have a PowerBook or whatever, you can get a PCMCIA wireless card to access a wireless network. The card itself has the MAC address, so it wouldn't know if it was plugged into your PowerBook or any other laptop running any other OS. \MAC addresses are the same as IP addresses in terms of OS filtering: there is none.

In order for a network to filter by OS, it would have to ask the host what OS it is running. That isn't hard to do. Your computer would communicate this information to the network, and the network would decided whether to allow you or not. THE NETWORK CANNOT DETERMINE YOUR OS BY IP OR MAC ADDRESS.

You bring up a good point. This leads me to believe that the MAC address filtering filters the MAC addresses of different types of cards, which makes more sense. To get around this I could either try to change my cards' MAC address somehow or buy a card typically used in Apple computers and install it in my laptop. Does it sound like either idea would work or am I still way off?

Hmm first off there is no way that you can just buy a apple card
Second of all, i still don't believe it will work

Theoretically yes, if this network is indeed filtering by MAC address. Heres a link that may be of use to you:
http://www.nthelp.com/NT6/change_mac_w2k.htm

I will say, if you can sniff the MAC address of an existing network node, it is possible to join the network using the MAC address of that node. I better not share the details though, because even if I do, the mods will just erase it.

Did I ever say this network was using OS filtering? No I didn't. Maybe you should read up on MAC address filtering:

BINGO! thats what I was saying the whole time...has nothing to do with the OS...as I said earlier MAC addresses are hardware specific not software. Although here is an interesting link:

Domo Arigatou Gozaimasu! (Thank You Very Much, super formal) The information all of you have given me has helped, especially the link at the end there with the directions for changing MAC address(es). Unfortunately, I will not be able to test it for about another month or so, but it sounds like I have a pretty good chance of succeeding!
