Our internet finally works!!!

However my fears have come true, as I don't have an ipv4 address of my own, just ipv6.

I really want my Webserver to be at home instead of having to rent some vserver.

Does anyone have any experience with webhosting when you only have ipv6?

I'm honestly kinda thinking about switching contract over to one that works with DSL. It'll be the same price for half the speed, but I should be able to get my precious ipv4 with it, and I also already have the router for it so it wouldn't really cost anything extra

Master IPv6 Neighbor Discovery Protocol (NDP) Networking

As the world moves towards IPv6 to accommodate the ever-growing number of devices, one key protocol makes sure everything runs smoothly: IPv6 Neighbor Discovery Protocol (NDP). This protocol is crucial for devices to find each other, configure their IP addresses, and ensure proper communication over an IPv6 network. In simpler terms, it’s like a “digital handshake,” allowing devices to talk and exchange important information seamlessly.

In this guide, we’ll break down the workings of NDP in a way that’s easy to understand, even for those new to networking. Whether you’re a network engineer, a student learning about IPv6, or simply someone curious about how your devices connect, this article will provide you with all the essential insights you need to master the IPv6 Neighbor Discovery Protocol and improve your understanding of IPv6 networks.

What Is IPv6 Neighbor Discovery?

Imagine you’ve just moved to a new neighborhood. You don’t know anyone yet and have no clue where the grocery store is or how to reach the nearest bus stop. Naturally, you’d walk around, introduce yourself, ask for directions, and gradually get familiar with your surroundings.

Choose platforms that align with your audience and goals. For more information on choosing the right platforms, check out this guide from Networkerden

Well, computers do something similar on an IPv6 network.

The Neighbor Discovery Protocol (NDP) helps devices

In simpler words, it’s the way devices on IPv6 networks say, “Hi, who are you?” and “Are we connected properly?”

In IPv4, we had something called ARP (Address Resolution Protocol). However, in IPv6, NDP is the new standard.

Key Features of NDP

Here’s what NDP does under the hood:

Each of these steps ensures devices can talk to each other smoothly and securely.

NDP Message Types

Let’s say you're new to a college campus. Here's how you might interact and how NDP mimics those interactions.

1. Router Solicitation (RS)

"Hey, is there any router out there?"

A new device (host) sends this message to discover local routers.

2. Router Advertisement (RA)

"Yes! I'm your router. Here are the network details."

Routers reply with necessary information like prefix, MTU, and default gateway.

3. Neighbor Solicitation (NS)

"Hey, I need your MAC address. Can you share it?"

Used to resolve the link-layer address of a neighbor or to check if a neighbor is reachable.

4. Neighbor Advertisement (NA)

"Here I am! Here's my MAC address."

Devices respond to NS messages, confirming they are active.

5. Redirect

"Hey, I’m not the best route. Use that other router instead."

Routers use this to guide hosts to better next-hop addresses.

Step-by-Step: How Devices Use NDP

Here’s a step-by-step example of what happens when your device connects to an IPv6 network:

What About Security?

NDP, by default, is a bit too trusting. That’s where SEND (Secure Neighbor Discovery) comes in, like installing a security camera on your network block.

SEND protects against:

It's not widely used everywhere yet, but it's available for high-security environments.

NDP vs. ARP: What's the Difference?

NDP is smarter, safer, and more flexible than ARP.

Why Should You Care?

Whether you’re a student, IT professional, or a curious tech enthusiast, knowing about IPv6 Neighbor Discovery Protocol helps you understand how devices "talk" on modern networks.

And if you're setting up IPv6-enabled products, routers, or even enterprise networks, this knowledge is crucial. When your network behaves strangely, it's often due to misconfigured NDP settings.

Planning to buy an IPv6 router or firewall? Now you know exactly what features to look for. make sure it supports proper NDP handling and even SEND if needed.

A Quick Anecdote: When NDP Saved the Day

Last year, an IT admin named Ravi was migrating a mid-size company's internal systems to IPv6. Everything seemed perfect — until random devices lost connectivity. After hours of debugging, it turned out that the Router Advertisement messages weren’t reaching all subnets.

A simple configuration of RA intervals and proper NDP multicast support fixed everything. The lesson? Never underestimate the power of protocol details!

FAQs About IPv6 Neighbor Discovery Protocol

1. What is IPv6 Neighbor Discovery Protocol (NDP)?

NDP is a system that helps devices find each other on an IPv6 network, get their IP addresses, and make sure they can communicate properly. It’s like devices introducing themselves and checking if they are on the same network.

2. How Does Neighbor Discovery Work?

NDP sends messages between devices. First, a device looks for routers. Then, it gets information from them. Devices also ask each other for MAC addresses to communicate. NDP also checks if two devices have the same IP address to avoid conflicts.

3. What Are the Benefits of NDP in IPv6?

c

Yes! NDP can be secured with Secure Neighbor Discovery (SEND), which uses encryption to prevent hackers from sending fake messages or intercepting communication.

I've been trying to set up a minecraft server, and i'm having problems with DNS.

I've been unable to access my stuff without the cloudflare proxy for some reason and cloudflare wants money if they're gonna proxy minecraft since it isn't http(s).

It's also kind of weird that i just can't access anything without a proxy. the AAAA record is set up propperly as far as i see, and i can connect with just the ip no problem. i don't really see what the problem is, besides that there isn't an A record.

Anyone got any ideas on how to fix that?

How to find your Apple TV's IPv6 address(es)

Since Apple TV's network settings don't list IPv6 info, it's time to get creative, though it won't be the hardest tech guide out there. Typically it has 2 IPv6 addresses: 1 public, and 1 private (The latter of which is used within the home's router network).

————————————————

Public IPv6 address

Download https://apps.apple.com/app/icurlhttp-appletv/id1153384808 (iCurlHTTP AppleTV)

2) Open that app. 3) In its "Browser" settings in the lower left, change from "User" to "iPhone". This is required. 4) In its address field in the upper left, write "https://ip.me". Then press the remote's OK button. 5) If it works, a row will show up a slight bit down in the text results that say "<p class="ip-address">" followed by your Apple TV's public IP.

————————————————

Private IPv6 address (i.e. within your router's LAN)

Download https://apps.apple.com/us/app/vlc-media-player/id650377962 (VLC for Apple TV)

2) Open that app. 3) Go to "Remote Playback" → Click "Turn On Remote Playback" if it hasn't already been turned on. 4) The app will show a URL that it tells users to open on a non-"Apple TV device". It will usually be "http://(The Apple TV's network name in lowercase with dashes).local" Ensure that the VLC app remains on that screen throughout the entire rest of the guide. 5) On a Windows, macOS, or Linux device (Android won't work), open any sort of command line (PowerShell, Cygwin, Windows Terminal, Command Prompt, Mac Terminal, Bash, ZSH, anything you can think of like those). It is not needed to run as administrator, though nothing bad happens if you do.

6) Type "ping (the URL from step 4 but without the http:// part)", then press Enter.

7) If it works, the result will show "Pinging (URL) [(The private IP address)] with 32 bytes of data:" 8) That IP (Remove the last "%(2 numbers)" part first) can then be pasted into a browser, "http://[(The IP)]". The square brackets are required. 9) If the browser loads a "Drop files" window, then the IP works correctly.
