IP question

Okay, so I received my FreeDesktopPC from Gratis yesterday. Would it be an issue completing existing offers on the new cpu or is it going to be a pain in the ass and tell them the situation for each site? I never seen a "hold" and I don't plan to, even in this case where THEY sent me this machine. Anyone run into this before?

COngrats on the free computer P
Its not gonna be an issue competing offers on the the new computer as long as you havent done them before.

You can change the network card to the new computer to keep the old IP address.

Your IP isn't determined by the computer. It's determined by your ISP.

Maybe you are thinking of MAC addresses.

Correct. Although they can track your MAC address as well (not sure if they do).

The main thing is you physical location and Internet Service Provider.

I'm sure you get your IP address from your MAC address[=http//www.webopedia.com/TERM/M/MAC_address.html]MAC address.

For ISPs, it's the MAC address of your modem. I don't know if the modem tells the ISP your network card MAC address.

For ethernet networks in universities, the MAC address of the network card since there is no modem obviously.

And, not telephone modems. They don't have MAC addresses I believe.

weez if you are currently posting from your new computer i show the same ip as all your previous posts hope that helps

No.

The MAC address of a network card is used on internal networks. It has nothing to do with the IP that your ISP provides.

The MAC address of your cable/dsl modem is used like this...

Home comp ----sending MAC address-----> DHCP service-----sending IP----> Home comp

Your local MAC address is just needed to communicate with your ISP so that it can distribute an IP to you. It has nothing to do with the IP number itself.

Exactly. You get your IP address based on your MAC address by the DHCP server. That's what I'm saying. Change your MAC address and you might be a different IP.

...no, you didn't read that right.

The MAC address is what allows you to communicate with the DHCP server but your IP is [i5112c0043f]not[/i5112c0043f] determined by it. That is determined by the ISP.

liCinn is correct. The way to change your IP is to ask your ISP, switch ISPs, or sometimes the ISP releases and renews IP addresses which might give you a new IP.

ISP = Internet Service Provider ie. Cox, AOL, Earthlink, etc.
IP = Internet Protocal (I think...)

Your MAC address is just an identifier. A unique name (sometimes... I beleive they have had to reuse old MAC addresses but I could be wrong. I have forgot a lot since my network classes).

Dial up Modems do not have a MAC address but they dial into a device with a MAC address which then assigns them an IP address.

li Crap what was I thinking... ignore the PM I just sent.

I think you meant Cinn. /

The best way to think of it is that your computer is stranded on an island. The MAC address is the signal flare shot into the sky to say "HEY COME OVER HERE AND RESCUE ME." The rescue ship is the IP, sent from the mainland which is the ISP.

What was I thinking...

Isn't your MAC address the same on any computer? Everywhere I've looked its 225.225.225.0

I assumed everyone has a unique mac address. This is unique for every computer. Every new computer has a unique mac address. IP is given out by ISP's. I thought that your comp sends out its own internal mac address to identify itself as a unique CPU on the network. I also believe this is what hackers use to sniff packets of data to capture your mac address so they can spoof their mac address to match that of an authorized user to gain access upon a secured wireless netowrk. From my understanding mac addresses and IP's are 2 completely things and have absolutely no relationship to one another

I also remember from my networking class that a router uses your mac address to identify which computer or device to send data into. Mac addresses are just used to identify which cpu or device packets needs to go to or whther or not a cpu or device is authorized for services. Ip addresses are just unique idetntifiers to a network. Think of mac addy as COMPUTER_ID and an ip addy as a NETWORK_ID. ie, if your on a large network(school/work) where many users share the same IP address(top level) but have different ip addresses given out by the routers of the network. (10.0.0.2) For access to the internet everything passes through the router or switch. Thus it is the master controlller of traffic. Ip addresses are dynamic and can change at any given moment. A netork needs your mac address to identify your comp as the one that needs to be giventhe packets. Long topic, Ill leave it here

someone please correct me if Im wrong or add any comments I may have left out

[quote88fce8dcac="good2speed"]I assumed everyone has a unique MAC address. [/quote88fce8dcac] They are like keys for a car, each one unique but there are only so many possible combinations. Card manufacturers are assigned a large block of addresses from the IEEE Registration Authority. My first car was an 87 dodge colt, I had a friend (oddly) who had a 78 Dodge colt and our keys were interchangeable (came in handy when playing jokes on each other). I "Believe" that I have read somewhere (Net+ cert) that they started reusing MAC addresses. Not a problem unless you happen have the exact type of card, happen to be with the same ISP, and happen to connect to the same DNS server.

DNS Domain Name Service

[quote88fce8dcac="good2speed"]This is unique for every computer. Every new computer has a unique MAC address. [/quote88fce8dcac]
Not exactly... this is "supposed" to be unique for every "Network card." I only mention that because my server has 5 NICs (Network Interface Cards) that means it has 5 MAC addresses and 5 (internal) IP addresses. Computers themselves do not have a MAC address without a network card.

True with one exception. "Hackers" or Security Specialists use utilities to capture packets (bits of information being sent across cyberspace). When they collect enough valid packets, they then can break the encryption and find the MAC address. There are utilities out there that can do it in seconds... others can take days.

So much for simple!!

Thats the subnet mask. You should be ok, cause your IP address will look almost the same if not the same. Lets say your original computers IP is 192.168.5.644 Your new computer would be something like 192.168.5.777. Only the last three numbers will be different.

(except for a select and rare insanely rich/lucky companies like Microsoft) the rest really depends on your ISP.

Example My internal IP address is 192.168...., but my external/internet IP is 68......

Everyone with a standard off-the-self Linksys, Netgear, or D-Link router will have an internal address of 192.168.#.# can change their "Internal" IP address by accessing the control panel of their router to any IP range (example instead of 193.... they want 193.... as long as it is not a special reserved range which I forgot the exact ranges), but that will not effect your Internet IP.

Your IP is SOLELY governed by your ISP who has a reserved block of IPs that they are aloted (again by the IEEE). IEEE altimately govern ALL IP and MAC addresses... though people/ governments want to change that.

Not only Microsoft I also belive any larger network uses different ip prefixes such as 10.x.x.x and a host of thers. I believe the 192 prefix is mainly used for small private networks. Or I think it might just be dependant upon the router you use

I think you are right about the 192 assigned to small [relatively] companies.

There also are a lot of "reserved" domains On top of giving companies "like" microsoft, novell, cysco, and a few universities and other companies so much because noone ever thought that the then strictly text/code based internet would ever be used by normal individuals. Internet was never planned to be this popular until the early to mid '90s. The "Internet" had been around for aproximately 50 years before its popularity exploded.

Now the IEEE is a lot more selective about what they give out.

As long as no "holds" are in place that's all that matters. Man you guys sure know your stuff. I'm still a little unsure, just gotta read it over and take a few notes. )

Most cable ISPs issue you an IP address based on your mac address. That mac address can either be from your router (if you have one) or from your computer's NIC. Most routers these days allow you to 'spoof' mac addresses to match the nic in your computer. This is because many restrictive ISPs only "approve" one mac address, and it's the address of the card in your computer when you first sign up (they wont support routers officially). So short answer, your public IP address is not necessarily dependent on your MAC address, but it often can be.
