Forum Thread: ipv4 and ipv6 Vulnerabilities

hi guys, so lately i found out that there are some security holes in ipv6..

should someone use ipv4 and ipv6 in the same time or just one of them? Does it differ if it's on the local internet or through wi-fi.Like should through wi-fi be used both ipv4 and ipv6?Or everytime one of them should be used..i'm confused.

What can be the risks??
how can you even get hacked by small vulnerabilities of that?

I would appreciate a reply as soon as possible.
Thank you
