Most solutions on search return the std.os.socket but os package no longer has the socket method defined.

const std = @import("std");

pub fn main() !void {
    const addr = try std.Address.parseIp("127.0.0.1", 8080);
    const sock_fd = try std.os.socket(std.os.AF.INET, std.os.SOCK.DGRAM, std.os.IPPROTO.UDP);
    defer std.os.close(sock_fd);
    
    try std.os.bind(sock_fd, &addr.any, addr.getOsSockLen());
    
    var buf: [1024]u8 = undefined;
    const len = try std.os.recv(sock, &buf, 0);
    std.debug.print("{s}\n", .{buf[0..len]});
}

I found the answer on Ziggit, posting it here for better reach.

Thank you dimdim for the solution.

const std = @import("std");

pub fn main() !void {
    const sock = try std.posix.socket(std.posix.AF.INET, std.posix.SOCK.DGRAM, std.posix.IPPROTO.UDP);
    defer std.posix.close(sock);

    const addr = try std.net.Address.parseIp("127.0.0.1", 55555);
    try std.posix.bind(sock, &addr.any, addr.getOsSockLen());

    var buf: [1024]u8 = undefined;
    const len = try std.posix.recvfrom(sock, &buf, 0, null, null);
    std.debug.print("recv: {s}\n", .{buf[0..len]});
}
