Why can't ISPs give me a "white" + "dynamic" IP?

Question

Computer networks

Explain to me one simple thing.
How many providers I call, they all offer me one of two things.

1) Dynamic IP + (Gray IP exposed behind NAT) Free.
2) Static IP + (White IP Public IP) Paid.

I need a Dynamic White IP.
Why are they technically, or why can't they give me a Dynamic White IP???
How many called, they all claim that they can’t do this, why is this so ???

There is another company, they initially give everyone White public IP addresses, and these addresses change when the router is turned off, for an additional fee they can give me a Static IP.

But why can't these previous companies provide me with a Dynamic White IP?
What's wrong with their equipment, or what's so special about their networks, line?

Thank you.

Answer 1

Because if you turn out to be a terrible spammer / hacker / phishinger, then in the blacklists, for example, of a spamhouse, there will be only one "white" IP, but if it is dynamic and you overload the router all the time, then a bunch of IP addresses will fall into the blacklists - and why does the provider need it?

Answer 2

Technically, of course they can. But they don’t want to, because you are such a plus or minus one, and the existing infrastructure is already configured for one of the options you specified. By the standards of the average ISP customer, you want the weird.

Answer 3

Buy a pool of white addresses, and download between them yourself. And if you want a budget - use a proxy and / or TOR. And the white address is needed not to access the outside, but vice versa.
Breaking down the infrastructure that has already been set up is the same as in a 9-story building, at the request of the owner of the apartment from the 3rd floor, to remake his ceilings by 340cm instead of 275cm. So - intelligibly?
Any provider has white IPs, but some have only 32 of them, while others have 65535. The question is - who can distribute them? And who has the opportunity to distribute? Will she pay off? Will reserving a list of addresses exclusively for one client also pay off? Monopoly - because other clients did not order such stupid jumping on free IPs.
PS If your IP is blocked - maybe you should think about the illegality of your actions from this IP? Have you been called to law enforcement yet?

Answer 4

Because everyone who needs a white IP, everyone needs a static one - in order to raise the service. Spammers need a dynamic white IP to spoil, and then say "I'm not me, #oops not mine."
After that, it remains to rake out the threshing floor from SpamHaus, barracuda and other blacklists. And the number of IPs they have is limited, because the free IPv4 blocks have long ended, now everyone is only buying up blocks of the "dead" (companies that registered the block, but left the market) or share what they managed to find.

Answer 5

Because free white V4s have long ended, new ones do not give out, what is now on the market - resale from one provider to another.
In order to recoup this purchase and resell them to willing customers, the rest, NAT is enough to sit in one-eyed glasses.
Some providers, at one time, managed to buy for the future and they still have enough addresses for clients, but as they are used up, they will also quietly transfer to NAT.
Well, as they wrote above in terms of border infrastructure, this also differs
