Why Doesn't ipfs id Show Yggdrasil Addresses?

 Title: Why Doesn't ipfs id Show Yggdrasil Addresses?

Intro:
Although IPFS nodes listen on Yggdrasil addresses, the ipfs id command often fails to display them. Here's an exploration of possible reasons and solutions to this issue.

Hashtags:

#IPFS #Yggdrasil #Decentralization #Networking #Troubleshooting    

This behavior may occur because IPFS doesn't explicitly advertise Yggdrasil addresses (ipfs id) by default, even though the node listens on them. Here's why this might happen and some potential solutions:

Reasons for Missing Yggdrasil Addresses:

1. Multicast DNS (mDNS) Scope: IPFS uses mDNS for local peer discovery, and Yggdrasil is typically treated as a separate layer-3 network. If the mDNS scope doesn't include the Yggdrasil address space, IPFS may not automatically announce those addresses.

2. Lack of Explicit Bindings: IPFS might not prioritize Yggdrasil addresses when generating the list of announced addresses, especially if they aren't explicitly defined in the configuration.

3. Yggdrasil-Specific Behavior: The Yggdrasil network operates differently from standard IPv4/IPv6 networks, and IPFS might not fully integrate with it for announcements without additional configuration.

4. Network Interface Filtering: IPFS could be filtering out interfaces linked to Yggdrasil due to their unconventional nature, especially if those interfaces aren't explicitly recognized.

How to Fix or Confirm the Issue:

1. Check the Listening Addresses:

Run the following command to see all addresses your IPFS node is listening on:

ipfs swarm addrs local

This should include your Yggdrasil address (e.g., yggdrasil-ipv6 format). If it's missing, the node might not be binding to the Yggdrasil interface properly.

---

2. Manually Announce Yggdrasil Addresses:

You can explicitly configure your IPFS node to announce Yggdrasil addresses. Add the Yggdrasil address to the Addresses.Announce section in the IPFS configuration file:

ipfs config --json Addresses.Announce '["/ip6/<yggdrasil-address>/tcp/4001"]'

Replace <yggdrasil-address> with your actual Yggdrasil IPv6 address.

---

3. Ensure the Node is Binding to Yggdrasil:

Check if the node is bound to the Yggdrasil interface. Add the Yggdrasil address to the Addresses.Swarm section:

ipfs config --json Addresses.Swarm '["/ip6/<yggdrasil-address>/tcp/4001"]'

---

4. Debug Logging:

Enable debug logging to see if there are any errors related to Yggdrasil addresses:

ipfs log level all debug

Look for logs mentioning your Yggdrasil address.

---

5. Verify with Peers:

If you’re connected to other nodes on Yggdrasil, verify connectivity by checking peers:

ipfs swarm peers

This will confirm if the node is successfully communicating over Yggdrasil, even if the address isn't displayed in ipfs id.

If none of these steps work, it could be a limitation or bug in the IPFS implementation when interacting with Yggdrasil. Consider reaching out to the IPFS community for further investigation.
