Does IPv6 slow 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.

Is IPv6 good to turn on

Enabling IPv6 probably won't speed up your internet connection. However, there are also notable benefits in IPv6 for mobile devices, which will be able to maintain the same address when moving from one connection to another — going from a 3G network to Wi-Fi provided by your local coffee shop, for example.

What are the disadvantages of IPv6

Disadvantages of IPv6

No backward Compatibility: IPv6 is not available on IPv4 machines, which means one can not run IPv6 on IPv4-supported machines. Conversion Time: The other major disadvantage of IPv6 is identifying the device on the network uniquely, and converting to IPV4 is very much.
