Why IPv6 is not widely used?

So if the protocol has been ready to roll for more than 20 years, why isn't it everywhere yet? Perhaps the primary reason IPv6 has been slow to take hold is because of network address translation (NAT), which has the ability to take a collection of private IP addresses and make them public.

Does IPv6 slow down WIFI?

If you have IPV6 turned on, DNS lookups are 2 to 3 times slower than with IPV4. That's why it seems as if your computer has "trouble connecting" to web sites. When you initiate a connection to any site, the first thing it does is look up the IP address in DNS. DNS lookups are slow on IPV6 for several reasons.

Can IPv6 cause lag?

As far as lag spikes are concerned using IPv6 makes sense because if you have IPv6 enabled those packets are being filtered and that for sure will cause lag spikes as well. Not to mention not having any QoS also on the IPv6 side.
