A question that has haunted me!

[forgoten]

Ok, maybe i slept that day in cisco. But something that has plagued me for ever is this:
1. how in the **** do we get ip's.... i know the basics dont talk to me like im 2, but i mean. Is there a super computer out there that tells every isp that this ip is available and this one isn't... when a computer is connecting it connects so fast, how can it search the entire internet. my best guess, is each isp is assigned to a certin range of ips... duno?

2. As far as MAC addy's go, every mac address is different, there is no isp controlling them. and there is multiple companys/manufactureres making them, how in the holy hell can there be a diff mac address for every nic card and/or modem.

3. And how can there be enuf ip's, i know the ips go from 0.0.0.0 to 255.255.255.255. but althought that is a **** load. Did mr gore forget to think about that when he created the internet. *hhahaahhahaha* sorry had to laugh... but yea, what are they guna do, if we run out.


Please help me sleep at night! :rolleyes:

I don't think we need to worry about running out of ip add... my math says that there is a possible 4,228,250,625 different ip addresses.... I think that's enough... even if it's not... then there is the subnet mask... adding an additional 4,228,250,625 subnet masks... comes out to 17,878,103,347,812,890,625... wow... i don't even know what that number is... hmmmm.... I hope that's right :p

yea we have already run out of ip addresses. thats why we have dhcp servers and subneting.

Forgoten, I would recommend censoring yourself with **'s or allowing forum software to censor you instead of intentionally bypassing it, it's the rules. :)

What you'll find is that 255.255.255.*** refer to subnet masks of varying sorts.

MAC addresses are unique to each piece of kit (computer, printer, NIC, etc, and are governed by an industry body, in the same way barcodes are..........

And IPv6. I forget how the scheme works exactly, but it adds an amount of ips that multiplies exponentially the current pool.

As far as how they are assigned..........All I can provide is guesswork!

next set of IPs that will come out is an octet(eight) of two letter/number combinations like a mac address


that is something like
5,070,942,774,902,496,337,890,625

or 35^16 I believe

also only about a third of the 255.255.255.255 are only used on the internet. THe rest is for testing and private networks.
