Where do IP addresses Come from.. REALLY? meaning the the far far back end.?

Question

Okay.
Me, on this computer I am hooked to the end of a cable serving DHCP. I have an internal non-routable ip address of 192.168.1.whatever. In turn that is translated to a static public IP-address served to us by a local company who in turn gets their IPs and bandwidth from At+t. That's as far as I can figure it.
I would like to know who or what lies at the root of the IP tree. What system or organization makes sure that the four and a quarter billion available addresses don't collide?

ghghghghghgh

Okay to clarify.
William V says

"There is a world-wide registry of IP addresses. Each Internet Service Provider is given a range of IP addresses to dole out to their subscribers."

Those guys..
Who are those guys.
Who's the illuminati of IP addresses. for DNS in this chunk of the world its ARIN. but DNS and IP are not the same.

Answer 1

There is a world-wide registry of IP addresses. Each Internet Service Provider is given a range of IP addresses to dole out to their subscribers. These are allocated in blocks from this pool of addresses. When an ISP gets a request to log on from a new subscriber, they loan out one of these IP addresses. When you disconnect, it's released back in the pool. Yes, many ISPs give you the same number each time but there is no guarantee of that.


Here ya go: (From Webopedia)

The four numbers in an IP address are used in different ways to identify a particular network and a host on that network. Four regional Internet registries -- ARIN, RIPE NCC, LACNIC and APNIC -- assign Internet addresses from the following three classes.

Class A - supports 16 million hosts on each of 126 networks
Class B - supports 65,000 hosts on each of 16,000 networks
Class C - supports 254 hosts on each of 2 million networks
The number of unassigned Internet addresses is running out, so a new classless scheme called CIDR is gradually replacing the system based on classes A, B, and C and is tied to adoption of IPv6.

There are DNS servers all over the world that share and synchronize a common database of names to IP addresses. When I want to setup a new web site, I go to the DNS registry company and tell them the IP address I have been assigned by my ISP. For a fee they record that address in the DNS database.

Answer 2

IP stands for intranet protocal, an IP address is a destination thats digitally assigned by an isp (internet service provider) so that when you exchange information with other computers or servers it can in simple terms have a conversation between computers and servers to deliver information to you.

Answer 3

Its the DHCP server on ISP's end that assigns IP addresses to the all the devices that register with the Server.
You can have your own DHCP server in your LAN which assigns IP Addresses to your home networking devices.

And this IP Address assignment is on the basis that ISP's have a fixed number of public IP's with them which they can sell. They might be having there private IP's that they might be giving to you.

sweetheart if you really want to know i can post the link of IP organization, but again it will takes time to read..

this is only 0.010% of all information, i don't want to blow your mind away with load of information
