Why can't I use this address?

Question

System administration

Hello. There is an organization that serves outsourcing companies. The customer wants the address 1.2.3.4.

Why can't he have that address?

Answer 1

And why, in fact, is not possible?
Inside the network, use any of them (since recently, relative to time, this is your personal crap )

Answer 2

I would doubt the adequacy of the customer :( 100% of the requests will not end there;)

Answer 3

Take 8.8.8.8, why waste time;)

Answer 4

Yes, because he is busy :)

Answer 5

and where does he want it?
if inside the LAN, going to the external through NAT - in principle, it is possible (while losing access to machines with IP addresses from the subnet that you will have in the LAN).
if as an external address - become the owner of an autonomous system and negotiate with the current owner of the IP address to acquire it. And, of course, prepare serious money for this.

Answer 6

And I would doubt the adequacy of the performer, who, judging by the tag to the question, is engaged in system administration, and at the same time cannot answer such a simple question on his own. :)

Answer 9

You can use it, raise the inner grid and there you can do whatever you want.
Configure DHCP and that's it, you will be happy.

Answer 10

So. Isn't it necessary to use addresses reserved for local networks within the local network?
