Steps to Reproduce and Observed Behavior

Running the following:

const std = @import("std");

pub fn main() !void {
    const addr = try std.net.Address.parseIp6("2001:db8:0000:0000:0001:0000:0000:0002", 0);
    const addr2 = try std.net.Address.parseIp6("2001:db8:0000:0000:0000:0000:0001:0002", 0);
    std.debug.print("Parsed address: \n{}\n", .{addr});
    std.debug.print("{}", .{addr2});
}

Gives the following output:

Parsed address: 
[2001:db8::1:2]:0
[2001:db8::1:2]:0

Expected Behavior

This is the correct compressed form:

Parsed address: 
[2001:db8::1:0:0:2]:0
[2001:db8::1:2]:0
