The strange IP address


I beg someone to look at the following question.

If your system is down, you can't log on to the Internet. Then you will get an automatic IP address from the system. I think it is generated byt the NIC card on your system.

What is it?

If u talk of the internet and u have a ADSL connection then that ip address (strange ip address) is assigned by your ISP.
Else the NIC doesn't start

Please do not post the same thread in more than one forum. Picking the most relevant forum and posting it once there makes it easier for other members to help you and keeps the discussion all in one place.

The original, and one with more answers, thread is here. This thread has been reported for closure.

It is not the loopback address. I am pretty sure about it.

Let us say that you can't log on to the Internet due to a failure in the NIC card, the system or rather the system will give you an IP address automatically though you can't go to the Internet.

[Xavier, I couldn't see my question on the Linux General Forum. I thought you removed it as it was not appropriate to that forum; because the question is related to networking. I know very well that the duplication of questions are not accepted.]

I assume you mean the 169.254.x.x address range. It's whats known as Automatic Private IP Addressing, I mostly see it on Windows machines where a DHCP server can't be found.

That is the one. You didn't know the exact host address too. There is an entire address.

I've never seen a Linux distro that assigned an IP address from that range automatically, I believe this is a Windows-only thing.

Is there someone who knows the entire address?

Exploding knew the network part.

I think that Gins thinks it is a specific and unique IP address in the above range. I'd rather suspect that Windows generates a random address every time and then tries to find out whether it is already in use.
Maybe there's more details in XavierP's links.

If you cannot see the network, Windows assigns the 169.254.xxx.xxx address.
