you can directly(open ports) connect with other ipv6 users, for ipv4 users you will get nat
Basically if you don't use dual stack you cannot connect with users, servers which are only using ipv6/4 .
ex- some govt website which is only running on ipv4, you will not be able to connect to it with only ipv6 .
