How to completely remove ipv6?

ipv6 is currently used in black deeds only!
ipv6 is needed for current purposes for hacking and similar cases.
I do not like it when the system has junk according to the settings, ipv6 is not used, then completely remove it, why keep it active ?!
I've heard enough.????
IPv6 is needed because the limited IPv4 address space is crippling the Internet and NAT breaks some things. Also, 4G and later cell network requires IPv6 support. IPv6 also provides some performance improvemance. In fact, some Microsoft stuff requires IPv6. For example their games set up a Teredo tunnel, if IPv6 isn't available and Windows HomeGroup also required it.
I've been running IPv6 on my home network for over 11.5 years.

Users are not calling their ISP saying hey I need IPv6 or going to switch.
The problem is, many don't even know about IPv6 and happily mess with NAT and STUN for games, thinking that's how networks are supposed to work.

I will remain unconvinced!
I will not prove anything.
But I know that ipv6 is useless for the current realities! -

As long as the big players, the major ISP's and dedicated server hosts, can include an IPv4 for your end device, for your router so you can have a 'real' IPv4 or your dedicated web server/mail server etc, the issue will be neutral for the public.
Right now, /24 blocks of IPv4 are still negotiated and sold among private entities, like our ISP's and other IPv4 consumers.
I don't know what the cost of a /24 IPv4 is these days, but it must be multiple digit number. And soon, if not already, this price will influence your monthly ISP fee. IPv4 will become a extra $$$ option.Assigning RFC1918 IP's as a WAN IP to end user might do the trick for some users, but it's considered a real pain. For example, VPN-to-home will be impossible.

We sold off a large chunk of our IPv4 /16 to major players ;)
If you can tell us :
What did this /16 cost initially ?
( and for what price were they sold ? ) -
@gertjan It probably cost nothing. it depends on if it was "Legacy" or not (Issued before December 22, 1997). The going rate for a /24 is probably about US$12,000. (All comments are WRT ARIN. Can't speak to other regions.)

Tell that to someone who's stuck behind carrier grade NAT and can't connect to their own network from elsewhere. There are a lot of those, some of them here.
The Internet was supposed to be transparent end to end. NAT breaks that, along with some other stuff.

This is me, unfortunately. Vyve Broadband bought my local cable company, and shortly after the transition was complete my service got moved one night out of the blue to CGNAT. Woke up one morning to notice my WAN IP had changed. My remote access VPN stopped working as did my Hurricane Electric IPv6 tunnel. And unless I am willing to tolerate much lower speeds, I'm stuck with this provider for now in my rural area.

Are they dual stack or strictly IPv4?

Only IPv4. I'm going to try going by the local office one day and see about getting moved back to one of their remaining non-NAT IPv4 segments. Don't know if I will be successful or not. My previous friendly tech contact has left their employ and moved elsewhere, so my inside connection is gone. All phone calls, even to the local number, now go to their call center in Texas or Oklahoma someplace.

I'm a lot luckier with my ISP. They've been providing native IPv6 for about 6 years and via 6to4 and 6rd tunnels for a while before that. They are also my cell phone carrier so not only does my phone get an IPv6 address, but so do devices I tether to it. Also, my IPv4 address is virtually static and the host name depends on my hardware MAC addresses, so I have no problems with connecting my VPN to my network.
