alt Hacker NewsI recently had to set up basic IP-based country detection in Nginx for a project. Parsing and handling IPv4 is trivial. The second I had to account for IPv6 string formats and update the Geo databases to match, the complexity just spiked for no good reason. It feels like we traded address exhaustion for parsing nightmares.

inet_pton/inet_ntop handle AF_INET6.
On one of my linux machines the "localhost:8080" did not work after new installation. It resolves to local ipv6 address, while server only listened on ipv4.
After this I go out of my way to disable, remove and nuke ipv6, out of every setup and deployment I do. Ipv6 is already quite complicated, but supporting TWO competing network stacks, with complicated pseudo compatibility, just multiplies unnecessary complexity!
