In one word: no. In more words: some addressing methods can lead to privacy and security issues, but those aren’t widely used anymore.
IPv6 addresses can be assigned to interfaces by several systems. One of those is SLAAC, or stateless address auto-configuration (comparable to APIPA and the 169.254.0.0/16 address space for IPv4). One method by which it generates globally unique routable addresses is by inserting the interface’s MAC address into the IPv6 address. Since IPv6 generally doesn’t use network address translation (and thus no masquerading), this would advertise your computer’s MAC address to the whole internet. More recently, SLAAC uses pseudorandom temporary (or “privacy”) addresses for interfaces, together with a unique network prefix assigned to the customer (analogous to the single public IPv4 address).
It’s also possible to assign IPv6 addresses statically or by using DHCPv6.
Doesn’t IPv6 offer less privacy?
Edit: thanks for the answers! Guess it’s a misconception.
Although ipv4 addresses still are easier to remember…
Only if you disable the pseudo address generation that is enabled by default on modern OSs.
No.

In theory, no.
In practice, yes.
No.
