(There is no version 1.16.221 of Minecraft: Java Edition.)
Still not working on 1.16.5 servers.
@Dungeneer In earlier versions, like 1.12.2 the structures are located based on the seed without loading/creating chunks.
I searched for open tickets, and didn't see MC-119840 since it was postponed at that time. 😞

Same crash in 17w17b
Fixed in 17w17a
1.0.1 is for iOS only, while the issue is affecting Windows 10.
The current implementation helps a lot of people with a shared IPv4 address. So they can set up a server and connect to it using IPv6. The server still needs IPv4 for the authentication servers, but not a dedicated IPv4 address.
I'm still hoping Mojang will enable full IPv6 support for all their services soon.
How hard can it be to implement a "use IPv6" checkbox in the launcher and some command line argument for the client?
There are plenty of options in the launcher that can seriously damage your game files and world saves. IPv6 wouldn't be one of them.
You could use the Forge client, it's removing this limitation. Unfortunately it's only available for 1.7.2.
IPv6 adoption is still very low in Sweden, so it won't be fixed by Mojang soon.
Related to MC-265250 which is closed as works as intended.
